Effect of Rigidity on Performance Level of Irregular Steel Structure

Recently, researchers pay attention to effect semi rigid conection on the steel structures. In this paper effect of semi rigid conections on the performance level of an irregular moment resistance steel structure with using pushover analysis is evaluated. The structure was designed optimizingly and then according to four different rigidity, which consist of 25%, 50%, 75% and 100% rigidity, is analyzed. The consider parameter is pushover curve and performance point. The results shows that structure with less 75% rigidity, perform life safety level according to 2800 code.
