An Investigation on Performance Based Design Determining the Effect of Facade Geometry on the Fire Ways

Historically, with the developing technology, the use of different facade materials and forms, which are the signatures of the architects in the high-rise buildings, have begun to appear as indispensable design entrances. Facade designs, which have become symbols of power and prestige concepts, have become one of the design criteria that should be given special importance in terms of fire safety. For this reason, it has been evaluated that it will not be possible to provide guaranteed and useful solutions for fire safety in the next generation building designs, which are prepared according to the traditional design rules and methods and the codes and regulations currently in force will not suffice. For a new generation of high-rise buildings to assist in the selection of fire-safe façade, a new concept, called performance-based fire design, Participation in the design of the fire has begun to gain importance in making the best technological solution, material selection and façade design. Performance-based fire safety under the modern new building structures to have fire-resistant performance in the shell of the facade systems in Turkey and designed according to the effects of the fire are the goals of the study. In the study, firstly the fire propagation mechanism on the facades will be examined. In this direction, it is aimed to investigate the examples of the necessary precautions and design decisions to be taken according to the results obtained when the concept of performance based fire safety is applied to contemporary facades and to try to determine the relation between facade geometry and fire propagation paths. In this respect, the evaluation of the performance of contemporary facade systems will emphasize the importance of the use of computer programs in the early design stage and that the laws and regulations in force will not be enough for today’s contemporary facade systems to provide fire safety.
