Study on Dynamic Analysis of Steel Structure with Different Types of Bracings

Authors(3) :-Karthik, Sridhar R, Kiran Kumar K L

The structure in high seismic areas may be susceptible to the severe damage. Now a days steel bracings in steel structure are most popular system to resist lateral load due to earthquake. Braced frame resist seismic excitation with comparatively less deformations than gravity load resisting system as they form a stiff system. Steel bracing is economical, easy to erect, occupies less space and has flexibility for meeting the required strength and stiffness. In the present work it is exposed, effect of seismic loading in 15 storey regular bare building using ETABS software. This buildings adapted different types of bracings such as diagonal, braced diagonal, X, K, K with bracing, chevron, braced chevron, V, eccentric diagonal and Knee bracings. The seismic response are evaluated by using equivalent static analysis, response spectrum analysis and linear time history analysis for bhuj earthquake data on Zone- V. Finally analysis results are carried out such as maximum storey displacement, inter storey drift, storey shear and natural time period. Based on the results regular braced buildings are compared and studied best braced structure to resist lateral loads. In three methods of analysis results in regular braced models, X bracings and chevron bracings system showed better resistance to seismic forces than the other specified bracing systems. The bracings provide adequate stiffness and continuous load path.
