BETONARME BİR YAPININ PERFORMANSA DAYALI TASARIMI: DEPLASMANA DAYALI SİSMİK YAKLASIM VE YERDEĞİSTİRME KATSAYILARI YÖNTEMİ Günümüzde kullanılan performansa dayalı tasarım metotlarından en yaygın olanı kuvvete dayalı tasarım metodudur. Ancak su bilinmektedir ki deprem sonucunda olusan yatay kuvvetler, yapıda yatay deplasmanlara, bu deplasmanlar da binada yapısal ve yapısal olmayan hasarlara neden olmaktadır. Bu hasar potansiyelini kuvvete dayalı tasarım ile kontrol altında tutabilmek yerdeğistirmeye dayalı tasarıma göre daha zordur. Kuvvete dayalı tasarımda, ön boyutlar belirlenir, daha sonra yapısal periyot ve elastik ivme spektrumu kullanılarak elastik spektral ivme katsayısı bulunur ve en sonunda elde edilen yatay deprem kuvvetlerine göre yapı tasarlanır. Yerdeğistirme kontrolü ise en son yapılır. Yerdeğistirmeye dayalı tasarımda ise, tasarıma hedef bir yerdeğistirme seçilerek baslanır. Yapılan çalısmada, doğrusal olmayan analiz yöntemlerinden biri olan yerdeğistirme katsayıları yöntemiyle doğrusal olmayan dinamik analiz yöntemi karsılastırılmıstır. Analizlerde SAP2000 programı ve Nonlin dinamik analiz programı kullanılmıstır. PERFORMANCE – BASED DESIGN OF A REINFORCED CONCRETE STRUCTURE: DISPLACEMENT – BASED SEISMIC APPROACH AND DISPLACEMENT COEFFICIENTS METHOD Nowadays, among the performance based methods, force based one is the most common method. But it must be known that horizontal forces which occur after an earthquake after an earthquake cause horizontal displacements and these displacements cause structural and nonstructural damages in the building. It is more difficult to bring this damage potential under control by force based design than displacement based one. In force based design, dimensions are determined, then structural period and elastic spectral acceleration coefficient is decided by means of elastic acceleration and in the end, the structure is designed due to the horizontal earthquake forces. Displacement control is performed in the end. As for the displacement based design, a target displacement is selected. In this study, displacement coefficients method which is an application of non-linear analysis methods and non-linear dynamic analysis method are compared each other. SAP2000 and Nonlin dynamic analysis programs are used in analyses.
The performance-based design of a concrete is the most common of the performance-based design methods used today is the power-based design method. But the water is known that the horizontal forces resulting from the earthquake, the horizontal movements in the structure, these movements also cause structural and non-structual damage in the building. Holding this potential of damage under control with power-based design is harder than ground-based design. In the strength-based design, the front dimensions are determined, then the elastic spectral vibration rate is found using the structural period and elastic vibration spectrum, and the structure is designed according to the horizontal earthquake forces eventually obtained. The control is the last. In the design based on landing, the design is pressed by selecting a target landing. In the drawing, the non-linear dynamic analysis method by the method of landing ratio, which is one of the non-linear analysis methods, is uninterrupted. SAP2000 and Nonlin Dynamic Analysis Program are used in analysis.
