In this paper the seismic performance of two dimensional braced steel frame structures with two story height bracings have been investigated. For the study purpose, Inverted V braced frames, Diamond braced frames and X braced frames are considered and seismic performance is compared with one story braced frame and bare frame structures. Varying aspect ratios (ratio of height of structure to base width) ranging from one to four are considered. Using ETABS, a finite element software, pushover analysis is performed to study the nonlinear behaviour of structure in inelastic zone. The results of the study indicate that, aspect ratio of one shows a better seismic performance when compared with rest of the models considered in the study. One story height braced frame structures have shown better seismic performance when compared to all other configurations considered.
