An Approach for Evaluating External Wall-Roof Coupling Detail’s Performance
(Konya Technical University Faculty of Architecture and Design, 2014) Türkay, Işıl; Altun, M. Cem
Designing a coupling detail is a complicated job since coupling details are areas where building elements and other sub-systems come together and performances of single building elements come into a complex interaction. Mistakes in the design stage can lead to building failures after construction, which on the other hand are causing unhealthy environments and high repair or retrofitting costs. The intersection areas in the external envelope, exposed to environmental conditions, are even more vulnerable to building failures. Building element systems of the external envelope do have several functions. Some of them are in common, but some functions are differing. These common and/or varying functions are coupled at the intersection area, working independently, cooperatively or opposing. This is why a complex interaction is born in a coupling detail. The coupling area of the exterior wall system with the roof system is one of those intersection areas of the external envelope. It is obvious that a way to avoid building failures is proper detailing. In this paper, an approach to evaluate external wall-roof coupling detail’s performance is presented. The evaluation approach consists of two modules. The first module is a “performance requirements checklist” separately generated for each building element, namely; the exterior wall systems and the roof systems. The second module is a step-by-step evaluation tool for coupling details. The tool and the checklists are prepared by taking into consideration of sole functional continuity at coupling details, supported by material continuity and geometric precautions. The evaluation tool can be used either in the detail design process or before the tendering process for finalized details. The usability of the proposed approach is demonstrated through its application on a real world problem and pros and cons of the approach are discussed in conclusion.
Usability of a Material Selection Tool for Architecture Students as a Sub Process of Building Element Design
(Konya Technical University Faculty of Architecture and Design, 2014) Koyaz, Mine; Altun, M. Cem
Material selection as a sub process of building element design is a hard task especially for the architecture students with a minimum material knowledge. In order to overcome such a problem one of the approaches is the use of methodical support tools within the process. With respect to that approach a systematic material selection tool is developed. The material selection tool intends to define the main steps of the process and to guide the students. In order to investigate the usability of the tool and for further development, the tool is applied by the 2nd year architecture students in Bilgi University as a part of their “Building Materials and Technologies” course and a usability questionnaire is conducted. In the paper, firstly the methodology of the work is explained; the development process of both, the “material selection tool” and the questionnaire. Secondly, the relationship of the material selection process with the architectural detail design process is issued. The application of the tool is stated and finally, the results of the conducted usability questionnaire are presented and discussed.
