000009469 520__ $$2eng$$aA study is performed on the system level performance of Braced Steel Frames. Two types of braced frames are investigated: Conventional and Buckling restrained steel braced frames. A methodology to evaluate the structural response of the building in a probabilistic framework is used. The procedure to estimate the probability of exceedance of engineering demand parameters (EDP) conditioned on the ground motion intensity measure is applied on the structures. Emphasis is given to estimation of the probability of exceedance of peak Interstory Drift Ratios (IDR). The peak interstory drift ratio provides a way to estimate the damage to structural components and some of nonstructural components. For this purpose a three-story structure, followed the criteria developed by SAC for an analytical study of steel moment-frame buildings, designed with both bracing types is used. Response of the structures under earthquake excitation was defined performing nonlinear dynamic analysis using OpenSees Framework. Based on the dates from the nonlinear dynamic analysis of the structures, the seismic fragility of the structures is developed. The results are presented as families of conditional probability curves plotted against the ground motion intensity measure and compared for each certain limit state.
