Seismic performance of different bracing for steel frames

Abstract

In today’s construction field material have very important role. Steel structures are more economical and can be used for long span members. So steel structures are preferred instead of concrete structures. To avoid damages during seismic activity steel structure should need to be more lateral stiffness and ductility. For this steel bracing are provided. Bracing transfer the lateral load due to seismic force and wind. There are different types of bracings are used in steel structures according to their placement and shape. Among the bracings, knee braced frame has excellent ductility and lateral stiffness. So, it has got more seismic performance. In this paper, a study on seismic performance of 4 different knee braced frames is to be performed. A static nonlinear analysis will be done using Ansys software. Results will be compared.
