Seismic behaviour of knee braced frame with different configuration

Authors(1) :-Asha Prakash P

In last decades steel structure has played an important role in construction Industry. It is necessary to design a structure to perform well under seismic loads. Its great strength, uniformity, light weight and many other desirable properties makes it the material of choice for numerous structures such as steel bridges, high rise buildings, towers and other structures. Steel structures in areas prone to high seismic activity should satisfy two main conditions. It should be stiff enough to control the drift to prevent structural damage, and also must have sufficient ductility to prevent collapse caused by dramatic deformation. Bracing element in structural system plays vital role in structural behavior during earthquake. Steel bracing is an effective and economical solution for resisting lateral forces in a framed structure. Knee braced steel frame is that which has got excellent ductility and lateral stiffness. Since the knee element is properly fused, yielding occurs only to the knee element and no damage to major elements. Compared to other type of bracings it performs better during a seismic activity. Aim of this study is to consider seismic effect of different types of steel knee bracings with different configuration in multistoried frame using ANSYS software.
