Comparison of Seismic Performance of Knee Braces in Steel Frames with Y Shaped Eccentric Braces
Today steel is the most useful building material in the construction field. Steel structures tend to be more economical than concrete structures for tall and large span buildings and bridges due to its large strength to weight ratio. The steel structures in the areas of high seismic activity should be stiff enough to prevent structural damage and have sufficient ductility to prevent collapse. Incidentally, steel bracing provides an effective and economical solution for resisting lateral forces in a framed structure. Among the bracings, Knee braced steel frame has got excellent ductility and lateral stiffness. Since the knee element properly fuses, yielding occurs only on knee element leaving the structural elements safe. In this paper, a study on the seismic effect of knee braced steel frames of different configurations were performed and compared with Y shaped Eccentric bracings, having a vertical shear link. Performance of the frames were studied using non-linear static analysis and non-linear time history analysis for various influencing factors.
