Abstract

The present study focuses on seismic performance of three dimensional braced steel frame structures by varying height of bracings in frame structure. The braces have been applied in three levels: one story bracing, two story bracing and three story bracings. For the study X-braced frames and Diamond braced frames with varying aspect ratios (ratio of height of structure to base width) ranging from one to four are considered and seismic performance is compared with bare frame structure. To identify the nonlinear behaviour of frame elements in the structure, pushover analysis is performed using ETABS software. The results of the study indicate that, aspect ratio of one shows a better seismic performance when compared with rest of the models considered. All braced frame structures have shown better seismic performance when compared to bare frame structure.
