Self-centering braced frames (SCBFs) and Buckling-restrained braced frames (BRBFs) demonstrate their advantages in seismic response due to no self-centering and buckling, respectively. This investigation focused on developing an improved understanding of challenges associated with computation of nonlinear response of two-dimensional building to recorded ground motions. For this purpose, two-dimensional models of not only self-centering brace along with buckling-restrained brace but also 6-story 10-m beam span of SCBFs and BRBFs – are developed in SAP2000 in order to compared to the result, which achieve from test perform and PISA3D study. The analysis of these models included cyclic pushover analysis for self-centering brace as well as buckling-restrain brace, in additional to nonlinear pushover plus seismic analysis for SCBFs and BRBFs at 4 ground motions recorded. It was found that modeling assumptions as well as different software may lead to significantly different response curves.
