Analysis of RC Building Frames for Seismic Forces Using Different Types of Bracing Systems

In this study, seismic analysis of high rise RC building frames have been carried out considering different types of bracing systems. Bracing systems is very efficient and unyielding lateral load resisting system. Bracing systems serves as one of the component in RC buildings for increasing stiffness and strength to guard buildings from the incidence caused by natural forces like earthquake force. In proposed problem G+ 10 story building frame is analysed for different bracing system under seismic loading. STADD-Pro software is used for analysis purpose. The results of various bracing systems (X Bracing, V Bracing, K Bracing, Inverted V Bracing, and Inverted K Bracing) are compared with bare frame model analysis to evaluate the effectiveness of a particular type of bracing system in order to control the lateral displacement and member forces in the frame. It is found that all the bracing systems control the lateral displacement of frame very effectively. However Inverted V bracing is found to be most economical.
