چکیده
In the recent severe earthquakes, it has been seen that existence buildings have high vulnerability. It is noticeable that the earthquakes caused extensive damage in the new constructed buildings, such as extreme structural or non-structural fractures. One of the prominent issues for the seismic design of structures is to estimate the reliability from the maximum value of structure deformations when the earthquake occurs. The main goal of this research is to determine the reliability index of serviceability limit state analysis of steel structures for their lateral deflection as the controller target function under critical excitation load. This study is very valuable for the following reasons: a) Effective quantities for the analysis and design of structures is stochastic generally and having the uncertainty. So, using the probabilistic analysis of reliability, the final result near the actual is found by influence of uncertainties. b) Applying the critical excitation earthquake for loading is so good to obtain the actual results with proper confidence margin. It is because of continuous frequency contents of such earthquakes which cause the most probable response of structure is created.کلیدواژه ها

COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.
کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
