Mevcut betonarme bir binanın sismik performansının doğrusal olmayan dinamik analize değerlendirmesi

Annually more than 17000 individuals are losing their life due to earthquake disaster in the world. For decreasing this number, structures must be performed by earthquake code to be designed for withstanding against ground motion. Aim of this earthquake codes are to minimize loss of life due to the collapsing the yielding building. Every country in the world has an earthquake code which analyzed and check structures with that but all of them are intend that structures resist large earthquake loading without life-threatening damage and specially without structure collapse or creation of large, heavy failing debris hazard. First earthquake code that had published building regulation enacted in Lisbon, Portugal. Turkey is one of the most hazard locations accordance to earthquake in the word. Most of Turkey settles on the active faults same as Anatolian tectonic plate. Since 80 years, 12 important earthquake was happened in Turkey that took lots of human life. Turkey is a historically place and most of structures are old so this structures must be analyzed and check that this building can be tolerance ground motion force. For analyzing the structure there are two methods. First is linear analysis that is divided to linear static analysis and linear dynamic analysis. In linear analysis, structural response is assumed that is linear and stiffness matrix does not change over the time. But with improving technology, it is cleared that structural behavior is not linear and go to nonlinearity against ground motion forces. Second method is nonlinear analysis that divided to nonlinear static analysis which a pattern of force is applied to a structural model that includes nonlinear properties. Total force against target displacement variation to define capacity curve-combined with a demand curve (typically in form ADRS) which cause the problem to single degree of freedom and nonlinear dynamic analysis that is a mathematical model directly incorporating the nonlinear load-deformation characteristics of individual represented by ground motion time histories. Nonlinear dynamic analysis is the most precise method but it is a complex method too because it needs a lots of information as input and take lots hours for analyzing so this method is used just for very important structures. For nonlinear dynamic analysis ground motion records are need but because we predict earthquake acceleration and we want to check this structures against future ground motion records, artificial ground motion records are used. This records are tougher that real earthquake records. In this thesis, different analysis methods are explained and then Kasimpasa building that is located in Istanbul is performed by nonlinear dynamic analysis. For analyzing of this structure, seven different ground motion records are used and then elements damage zone were defined by 2007 Turkish earthquake code and shear force and displacement of this building had been checked with 1975 earthquake code because this building was built in 1979 and it must be analyzed with this code. In conclusion, because some of elements (columns and beams) are located in collapse damage zone so this building must be retrofitting before usage.
