Dünyada yaygın olarak ulusal ve uluslararası yönetmeliklerde performansa dayalı tasarım prensipleri kullanılmaktadır. 1990’lı yıllarda meydana gelen depremler sonrası hasar alan yapıların tekrar kullanılamaması sebebiyle ağır ekonomik kayıplar yaşanmıştır. Sonrasında birçok yönetmelikte yapıların deprem sonrası kullanımı sağlanacak şekilde hedef performansa göre tasarımına yer verilmiştir. Türkiye Bina Deprem Yönetmeliğinin (TBDY) 2019 yılında yayımlanmasıyla birlikte yapı-zemin etkileşimine daha fazla önem verilmiştir. Bu doğrultuda ilk kez düşey yer hareketi spektrumu tanımlanarak kullanılmaya başlanmıştır. Ayrıca deprem tehlike haritaları yayınlanarak her bölge için spektral ivme katsayıları tanımlanmıştır. Bu çalışma kapsamında Türkiye Bina Deprem Yönetmeliğine göre mevcut betonarme bir binanın performans analizi yapılmıştır. Deprem Bölgelerinde Yapılacak Binalar Hakkında Yönetmelikte (2007) mevcut binaların performans analizinde şekil değiştirme esaslı yaklaşımlar tanımlanırken, TBDY-2019’da ilave olarak yeni binaların tasarımında da şekil değiştirme esaslı yaklaşımlara yer verilmiştir. Bu çalışma ile yeni yayınlanan yönetmeliğin uygulama esasları araştırılmıştır. Çalışmada TBDY-2019’a göre hesaplanmış düzensiz bir yapının performans durumu incelenmiştir. İnceleme sonucunda kontrollü hasar performans düzeyi hesaplanmış yapının yeni yönetmeliğe göre hesap detayları gösterilmiştir. Tüm aşamalarıyla anlatılan düzensiz yapıların performans analizi konusunda, çalışma sahasının genişletilmesinin uygun olacağı düşünülmektedir.
In the world, performance-based design principles are widely used in national and international regulations. Due to the earthquakes that occurred in the 1990s, the structures that were damaged were unable to be reused due to heavy economic losses. Therefore, a number of structures have been designed according to the target performance in order to ensure the use of the structures after earthquake. With the publication of the Building Earthquake Regulation (TBDY) in 2019, more emphasis has been given to the interaction between building and land. For the first time in this direction, the spectra of earth movement has begun to be used by identifying the spectra. Also, the earthquake hazard maps are published and the spectral drive ratio for each region is defined. Under this study, the performance analysis of a existing concrete building has been carried out in accordance with the Turkish Building Earthquake Regulations. In the Regulation on Buildings in Earthquake Areas (2007) the performance analysis of existing buildings defines approaches based on shape change, while in TBDY-2019 the design of new buildings also includes approaches based on shape change. The newly published regulations are conducted by this study. The study examined the performance status of an irregular structure calculated according to TBDY-2019. The review results showed the account details according to the new regulations of the calculated structure of controlled damage performance level. With regard to the performance analysis of the irregular structures described in all the stages, the expansion of the workplace is considered appropriate.
Performance-based design principles are widely used in national and international regulations in the world. Since the structures damaged after the earthquakes in the 1990s could not be reused, high economic losses were experienced. Later, in many design codes, the design of the buildings according to the target performance was provided so as to ensure the use of the buildings after the earthquake. Turkey Earthquake Building Code (TBDY) is given more importance to the soil-structure interaction with the release in 2018. Accordingly, the vertical ground motion spectrum has been defined and used for the first time. In addition, earthquake hazard maps were published and spectral acceleration coefficients were defined for each region. In this study, a performance analysis of the existing reinforced concrete buildings by the Building Turkey Earthquake Building Code is made. In the Code on Buildings to be built in Earthquake Zones (2007), deformation-based approaches are defined in the performance analysis of existing buildings, while in addition to TBDY-2018, deformation-based approaches are also included in the design of new buildings. With this study, the application principles of the newly published code were investigated. In the study, the performance state of an irregular structure calculated according to TBDY-2019 was examined. As a result of the examination, the calculation details of the structure, for which a controlled damage performance level was calculated, according to the TBDY-2019 code was shown. In terms of performance analysis of irregular structures, which are described in all stages, it is considered to be appropriate to expand this study field.
