Abstract

In past decades, the steel structures have played an important role in growing construction industry. It is essential to design a structure to perform well under earthquake loads, especially in seismic prone areas. The seismic design of a multi-story steel frame building is carried as per IS 800: 2007. By introducing steel bracings in a structure, its shear capacity can be increased. They can be also used as strengthening an existing building. In various patterns steel bracings can be arranged. A 15-story steel frame building is designed for eccentric K- and V- bracings as per the IS 800: 2007. Eccentric K and V type bracings in a steel frame having different configurations are selected for this study. Performance of the each frame is studied under Response Spectrum and Time History analysis. The results of analysis have shown that, performance of the eccentric V-bracing system is better than eccentric K-bracing system.
