Based on comparative analyses, it is concluded that the targeted and desired results are obtained.Öğe Architectural education based on integrated design and its effects on professional life(CRC Press/Balkema, 2023) Yazıcıoğlu, Zeynep; Dikbaş, Hüseyin AtillaConstruction industry needs innovations to increase productivity. One of the essential steps taken in this sense is BIM technology in project development. Rather than being a tool for drawing projects, BIM simulates cost, time and quality of construction works. Architecture schools should equip students with BIM knowledge because they are the potential professionals of construction industry. The settlement of BIM in the education programs are carried out in many different approaches of the undergraduate departments. Istanbul Medipol University is a non-governmental university in Turkey that aims to provide interdisciplinary education environment. Architecture, Interior Architecture, Landscape Architecture, and Industrial Design Department students work together on the same project by setting up teams. The aim of the program is to improve working skills with an Integrated Design approach, to educate professionals who are ready to work interdisciplinary in practical life, and to increase the efficiency of the studies from design development to construction with opportunities of BIM. In this paper, the effect of using BIM in the practical life, interdisciplinary working skills and integrated design awareness of the graduates will be investigated through a survey, and it will be concluded whether the education program has reached its goal. For this purpose, a survey for graduate students is prepared for getting feedback of their experiences in their professional life. Within the scope of quality, it is planned to improve the program by combining the survey results and literature research studies.Öğe A decision support mechanism for LEED building design & construction: Transit stations(Istanbul Technical University, 2020) Akarcalı, G. Z.; Cenani, Şehnaz; Çağdaş, GülenLeadership in Energy and Environment Design (LEED) is one of the most known and widely preferred green building certificate that is provided by the United States Green Building Council (USGBC). Among the several certificate types of LEED, the most recent one is LEED Building Design and Construction: Transit Stations (LEED BD+C: TS), published in order to meet the requirements of transit stations with the valuable input obtained from the metro corporations in India and China. LEED BD+C: TS leads to a complicated decision process that requires multidisciplinary collaboration during decision making process, technical expertise and experience of the decision makers, and investment assessment. In this paper, a decision support mechanism is suggested for such decisionmaking process. This decision support mechanism utilizes Analytic Hierarchy Process Ranking method, aiming to provide an insight for the decision makers to choose the most efficient LEED credit alternatives in terms of LEED Certification achievement. The proposed decision support system will be tested on a metro station construction in Istanbul Turkey that the first Author has professional experience on, as a case study.Öğe Deprem kaynaklı tsunami durumunda tahliye için karar destek sistemi önerisi: Kadıköy Caferağa ve Osmanağa mahallelerinde vaka analizi(İstanbul Teknik Üniversitesi, 2021) Efendioğlu, Gizem; Cenani, ŞehnazUzun bir deprem geçmişine sahip İstanbul, Kuzey Anadolu Fay Hattına yakınlığı dolayısıyla deprem açısından riskli bir konumda yer almaktadır. Yaşanan son depremden itibaren geçirilen süreç içerisinde, İstanbul yakınında bulunan fay hatlarında bir enerji sıkışması olabileceği belirtilmektedir. Bu sıkışma sebebiyle önümüzdeki 30 yıl içerisinde İstanbul’da 7.0 ila 7.4 şiddetleri arasında gerçekleşebilecek büyük bir deprem öngörülmektedir. Depremin neden olabileceği can kayıplarının yanı sıra İstanbul, kıyı şeritlerinde yaşanabilecek bir tsunami tehdidi ile de karşı karşıyadır. Olası bir deprem durumunda tsunamiye karşı 3 dakika içerisinde önlem alınması gerektiği belirtilmektedir. Literatürde İstanbul özelinde yapılan çalışmalarda tsunaminin kıyı şeridine ulaşma süresi 8 dakika olarak belirlenmiştir. Bu nedenle depremin ardından 8 dakikalık süre içerisinde hızlıca kıyı şeridi tahliye edilmelidir. Karar Destek Sistemleri (KDS), afet durumlarında hızlı ve isabetli kararlar alınmasını sağlayan bilgisayar destekli sistemlerdir. Bu sistemler dünyanın çeşitli bölgelerinde gelişebilecek afet durumlarına karşı hazırlıklar için kullanılmaktadır. Bu çalışma, İstanbul’da deprem kaynaklı tsunami durumlarında kullanılacak tahliye rotalarını belirleyen bir KDS önerisi sunmayı amaçlamaktadır. Çalışma, pilot bölge olarak yarımada konumunda bulunan Kadıköy Caferağa ve Osmanağa Mahallelerini incelemektedir. Önerilen sistem, anlama, tasarım ve karar verme aşamaları olmak üzere üç aşamada geliştirilmiştir. Anlama aşaması, sorunun analiz edilmesi ve yapılandırılmasını; tasarım aşaması, alternatif çözümler üretilmesini ve son olarak karar aşaması, karar verme durumunu tanımlamaktadır. Bu bağlamda anlama aşamasında pilot bölge analiz edilerek işlevsel, demografik ve coğrafi özellikleri açısından değerlendirilmiştir. Oluşturulan DEM (Digital Elevation Model) haritası ile tsunami açısından riskli bölgeler belirlenmiştir. Riskli alanlar sonraki aşamada çıkış noktaları için tanımlanırken, varış noktaları için bölgedeki hastane ve toplanma alanları belirlenmiştir. Tasarım aşamasında riskli bölgelerden varış noktalarına tahliye için rotalar geliştirilmiştir. Rotalar oluşturulurken, daha isabetli hesaplamalar yapılabilmesi için gerçek zamanlı trafik yoğunluğu analizleri sisteme aktarılmıştır. Daha güvenli rotaların belirlenebilmesi için ise anlama aşamasında belirlenen tahliye aşamasında riskli olabilecek bölgeler senaryolara dâhil edilmiştir. Araç ile ulaşım ve araçlara erişim olmadığı durumlarda yürüyüş rotaları için iki farklı senaryo oluşturulmuştur. Son olarak karar aşamasında, deprem kaynaklı tsunami durumlarında tahliye rotalarının oluşturulmasını sağlayacak bir Karar Destek Sistemi önerilmiştir.Öğe In-vehicle personalized routing for a heterogeneous group: An experience-based method for decision support system(2021) Çavuş, Özlem; Cenani, Şehnaz; Çağdaş, GülenCustomized navigation devices allow personalized routings based on user preferences. In determining common preferences for multi-user, it may become di cult to meet at a common point due to conflict of interests. A decision support system could serve as an asset to increase the quality of decisions users take. In conventional systems, decision making ties to pre-defined preferences of a single user or a homogeneous group.Öğe Social justice in architecture(International Organization Center of Academic Research, 2016) Ergül, HamdiThe concepts like "earn more, spend more and consume more", which came into being with the globalization process brought with them the social injustice and inequality issues. This situation is visible in every aspect of life (education, health, politics, etc.) as well as in architecture. Social stratification and the contraction of mutual living areas led to the increase in the gap between life standards with each day. When the supply-demand balance shaped by the building sector, human labor and the contribution of other sectors, which continue their activities depending on the building sector are considered together, it is observed that the share of the building sector in the GNP is around 35%. With the influence of capitalism, the buildings that cover the need for accommodation have been converted into money sources and investment tools that provide profit, which are all far from their actual purposes. Today, companies and countries acquire incomes via various sources. Architecture and the building sector have become the lead actors of this income and investment search. Despite this huge income, the human labor working in the sector cannot earn at a sufficient level when compared with the manpower provided by them, and when the difficulties and risks are taken into consideration. Despite the added value they lead, they live in unhealthy places and cannot become the owners of their own houses. The building sector is at a position that forms demands for the products and services produced by more than 200 sub-sectors connected with itself; and this common influence is the most basic indicator of the sector's being "the lead actor". The social status of the building sector and architecture, which deals with the design business of this sector will be dealt with in this study. The relation between the basic rights like environment, human rights, social justice, organic nutrition, drinking clean water, breathing clean air, residing at a calm house, freedom and the right of privacy, watching a beautiful scenery from the house, being protected from carbon dioxide and air pollution, which are the innate rights of every human being, in the ever-developing world will be discussed. While, on the one hand, the injustices in social and economic areas lead to chaotic environments in every geographical area, today's architecture only dealing with the design of the houses, work places, and residences where only aesthetics and image are in the forefront is not an ethical manner. The desire of the human beings to shape the buildings around them and the influence of this desire to show their belongings look more powerful than they normally are, and the influence of the advertisements prepared the suitable ground for the formation of "consumption architecture". Based on the principle requiring that the desires have to be fulfilled in the legal framework and in accordance with the human and environment, the problems have to be resolved by caring for the Balance and Justice. In the light of the Verses of the Quran "There has appeared corruption both on land and in the seas because of what men did with their own hands. Allah makes them confront the results of some of their deeds so that maybe they will return from the wrong." (The Surah, Rum; Verse 41), we can observe how the balance has been disrupted, how the societies went astray; and when they went astray, the disruption occurred not only in the field of ecology but also in the field of human relations and social problems. We can also see that when disruption starts in the balance, everything in the universe is influenced by this disruption at the same rate. In order to correct this disruption and balance, every aspect of life, from our own lives to architectural buildings in the world, from economic systems to legal systems have to be corrected. The message is being conveyed to us that the salvation and balance will be corrected if we develop new models in order to revert from this chaotic atmosphere. The knowledge and the acquisitions of human beings are sufficient to form the structures that will care for the justice and balance. In this study, the necessity of converting from consumption architecture into "social and just architecture" is being emphasized.Öğe Mobile technology and social networks: Mapping architecture students' practice and awareness for educational possibilities(IATED-INT Assoc Technology Education & Development, 2017) İlter, Akın Tolga; Karaçar, PelinMobile technologies are spreading our daily lives by the help of social media applications. Teenagers and young adults are among the highest percentage of smartphone and social media application users. As an apparent result colleges and higher education institutions are facing an increasing pressure to limit and control students' smartphone and social network use as these practices are accepted to be distracting. On the other hand, academicians are also tending to spend more time with their mobile devices and use social networks. At the brink of a connected World with the Internet of things', it seems things will get tougher to leave these devices out of classrooms. Although the idea of using such applications for the good of education is being discussed for some time now, research on using such tools and technologies for undergraduate architecture students is far from being extensive. Besides, existing data and insights are postulant to become irrelevant with an unusual pace. By the help of a survey data this paper tries to pin undergraduate architecture students' smartphone and social network practice and discuss their possible consideration for educational purposes. Initial findings give clues about some of the web 2.0 tools can help students enhance their design activities.Öğe Design-build workshops in architectural education. A case study; adobe bus stop in northern cyprus(IATED-Int Assoc Technology Education & Development, 2017) Güner, Aysun Ferrah; Benli, Gülhan; Karaçar, Pelin; Kasapseçkin, Mustafa AdilThe design-build workshops became a significant pedagogical tool to expand student learning experiences in practice environment. The aims of the workshop are to apply teory-practice and design-build as whole process, to understand design, building techniques, material and to improve student practical skills.The workshop was organised by Istanbul Medipol University, the school of fine arts, design and architecture in the education year of 2015-2016. After the second semester twenty first-year students, four lecturers from architecture and interior architecture programmes worked in the design-build teams.At first a research seminar was organised to develop a clearer understanding of the project objectives such as the need of project for community of Northern Cyprus, the usage of adobe which is a traditional building material of region, sustainable design, resource conservation etc. The design opportunities from ideas to building were explored with the second seminar and the team developed the design project for construction. Before construction a local specialist made another seminar to explore the material of adobe, features, techniques etc.The workshop was an example in which students design and built an adobe bus stop. Besides understanding of design, adobe as building material and the all process another important feature of our design-build workshop was the exploration of sustainable design which includes cultural and historic preservation.Thus, the paper will have all of the details regarding to the design-build workshop the predesign, design, build process and student approaches on learning outcomes.Öğe DEM analysis of passive failure state behind a rigid retaining wall: Effect of boundary conditions(EDP Sciences, 2019) Altunbaş, Adlen; Soltanbeigi, Behzad; Çinicio?lu, ÖzerDiscrete Element Modelling (DEM) is a virtual testing method that enables multiscale studies on granular materials. DEM provides a well-controlled testing environment, which enables precise systematic evaluation of the factors influencing the bulk response. The current study focuses on the behaviour of cohesionless backfills while a passive state of stress is simulated (i.e. rigid retaining wall translates toward backfill). Though particle-scale properties (e.g. size, shape and cohesion) play an important role on the macro response, the main objective in this study is to highlight the extent by which boundary conditions are important. Thus, identical dense packings are subject to the following boundary conditions: smooth/rough retaining wall and smooth/rough/periodic sidewalls (necessary for maintaining plain-strain conditions). Based on the DEM results, the failure surface geometries, wall pressure distribution and dilative response of the specimens are evaluated. It is seen that a curvilinear slip surface, similar to that observed in experiments, is only obtained once a rough retaining wall and periodic sidewalls are available. The overall observations suggest that the mobilisation of the passive state of stress, for a cohesionless granular assembly, is highly sensitive to the considered various boundary conditions.Öğe Happy city: City discussions(Sakarya University, 2015) Sağdıç, Zafer; Aydın, AysunCity, to where the citizen belongs to as being the citizen, thus having an identity with the city, to live in the city, with or without the rights of the citizenship. Well, on which point will the citizen be right- while living inside the city/ while trying to live on the city-? If being happy/ living happy is the will of each and every of us, who is going to create this happiness to us? we? or the others? who else? the country? the government? or the authorities? or the capitalism that we live for? or it’s new face , the neo-liberalist economies? Well, where is the citizen undercover on the city? till where is the citizen right inside the city? Every city user has a dream, an illusion, an imagination not only related with the city, but also about living on that city; and if the citizen has a utopia, then whose dystopia would it be. In other words whose utopia can be who else’s dystopia? Or whose utopia is a dream as having a mythical origin in the city where he lives? Searching, discussing, rejecting the “happy city “ are just some words of the lullabies of our childhood days? Or can those concepts be the basic points of our daily life? Each and every citizen has a dream in the city, being happy on the city by living the dreams or rejecting the city after seeing a nightmare. Being a refugee in a city, converge of a place in the city, being a part of myth of feeling himself as a citizen and soon rejecting the city life, and the dreams of being the other, living outside of the city, so on so forth. Which feeling must be the right to choose, to have to live a better life? Thus, the paper will be about the Happy City Workshop, which was held on Trabzon in 2014, during the architectural workshop series of Karadeniz Technical Universty and the short movie of the workshop that was shot in there by 15 students. The paper also will not only have all of those discussion about the relationship among the city, the capitalism, the neo-liberal economies and the architecture, but also it will discuss the utopias and dystopias related with the happy city and all who are searching of, living on, discuss and examine the city, who has an utopia of the city, or who see that all of the utopias of the city can be dystopias as well of others, and those who reject them all, while put a light to the written texts chronologically about the city from the first city focused written text of St.Augustin’s The City of God to Renzo Piano’s city discussions and Charles Mongomery’s book of Happy City. © The Turkish Online Journal of Educational Technology.Öğe A review of resource based view in the construction industry: A BIM case as a strategic resource(CRC Press-Taylor & Francis Group, 2016) Geylani, Özlem; Dikbaş, AtillaResource Based View (RBV) as an economy based strategic management theory, became an important management strategy for project management executives during the last decade. On the other hand, Building Information Modelling (BIM) is a valuable resource that projects and other outputs produced by its software leads the firm to differ in the market and may be considered as a strategic resource for the construction firms. This research will present the findings that are gathered from a case study in one of the Turkish light steel prefabricated construction firm, which has a new step with the Building Information Modelling system implementation including its tools and capabilities. This paper aims to test the Resource Based View in Turkish construction industry, while applying the BIM as a strategic resource within the environment of project management. Moreover, future research will take a closer look at the outcomes of the case study of this research, such benefits of the BIM as a strategic resource may be revised for other research studies, the outputs of the case study as a time study, has additional benefits for the construction firms such as; re-organization of the organizational structure of the firm, team development of the BIM execution plan, human resource management, the management strategy development for the firm.Öğe Contractual and legal issues for building information modeling in Turkey(CRC Press/Balkema, 2016) Sözen, Zeynep; Dikbaş, AttilaBIM is being used with increased frequency by Turkish contractors on building and infrastructure projects in Turkey. Although there is agreement among Project stakeholders that BIM is a valuable tool in the achievement of project goals and the management of projects, a full fledged implementation of BIM is not yet achieved due to several issues. The present paper shall attempt to identify a range of contractual and legal issues concerning the implementation of BIM in Turkey. The contractual and legal issues that present barries to the full implementation of BIM may be categorized under the following headings: the legal framework, liability and responsibility, confidentiality and traditional approaches to damages. The legal framework in Turkey lends more support to a fragmented structure within the construction industry, delineating the rights and responsibilities of the parties clearly. Current intellectual property law may not be adequate with the enhanced use of BIM in a contract. Furthermore traditional approaches to contractual liability and responsibility favour clear cut allocations of risk between the designers, contractors, subcontractors and owners. BIM allows the sharing of information between the project parties and authorisation of access to otherwise confidential data. The present tendency of the parties is to protect commercial information and to preserve commercial competitiveness. Finally the traditional approach to contractual damages is another factor stifling the widespread use of BIM in construction projects.Öğe Parametric BIM façade module development for diagrid twisted structures(International Association for Automation and Robotics in Construction I.A.A.R.C), 2018) Akkoyunlu, TahirBuilding Information Modelling (BIM) is an epochal phenomenon in AEC. Most of the developed countries has already adopted BIM by regulations. Biggest projects around the world executing by BIM which provides more effective project management process. Whole construction progress including; feasibility, design, construction and commissioning became digital visualization. Any required analysis can be done via this model template. In fact, requesting the complex and sophisticated structures’ construction is the main catalyst of developing BIM. Mankind start to design and construct cutting-edges and pushing limit structures. Twisted towers are one of the significant instance of like these structures. This study embrace the twisted towers’ façade design which has one of the most complex patterns. So it is thought that if such these towers’ façade system can be organized and customized limitlessly, most of the façades systems will be solved for the optimum result. This study aims to reveal a method which can be used for to develop easily alternative façade systems for construction projects even they have very complex design. One of the most complex structures the twisted diagrid systems which are constructed currently around the world was selected. BIM and computational programming have been used to improve the module.
