نوع پژوهش	مقاله چاپ‌شده در مجلات علمی
کلیدواژه‌ها	sensitivity analysis, material nonlinearity, geometric nonlinearity, RCMRF, pushover analysis
چکیده	Design sensitivity analysis is a necessary task for optimization of structures. Methods of sensitivity analysis for linear systems have been developed and well documented in the literature; however there are a few such research works for nonlinear systems. Nonlinear sensitivity analysis of structures under seismic loading is very complicated. This paper presents an analytical sensitivity technique for Reinforcement Concrete Moment Resisting Frames (RCMRF) that accounts for both material and geometric nonlinearity under pushover analysis. The results of proposed method are compared with the results of finite difference method. A three-story, two bays moment frame example is used to illustrate the efficiency of the method. This technique can be very useful and efficient for optimal performance-based design of RC buildings.
