Kumar, R (2014) Seismic analysis of braced steel frames. BTech thesis.
The study of braced steel frame response is widely studied in many branches of Structural engineering. Many researchers have been deeply studying these structures, over the years, mainly for their greater capacity of carrying external loads. Every Special moment resisting frames undergo lateral displacement because they are susceptible to large lateral loading. The problems associated with this are the P-∆ effect and the ductile and brittle failure at beams and columns connections . As a consequence, engineers have increasingly turned to braced steel frames as a economical means for earthquake resistant loads. The present study consist of two models. Model 1 is a Steel Moment Resisting Frame (SMRFs) with concentric bracing as per IS 800-2007. Cross bracing, diagonal bracing and an unbraced frame is considered for study. Model 2 consist of two Steel Moment Resisting Frame with similar V type bracing and Inverted V (Chevron bracing) configuration, but with varying height. Performance of each frame is studied through Equivalent static analysis, Response Spectrum analysis, and linear Time History analysis.
