Seismic Performance of Y-Braced Frame with Double Round Steel Tube

Seismic performance of Y-braced frame with double round steel tube aims to study the performance of the Y shaped bracing in a frame under seismic forces. The project involves the designing of the double round steel tube which act as a damper in the frame. The optimum size of the damper or the double round steel tube is to be identified by varying the dimensions in terms of height, thickness, diameter and length. Any one of the parameters is changed keeping all others constant to find the better resulting one. All most 20 combinations were done to find the optimum sized one. Optimization aims to achieve the best yielding damper to be placed. After optimization, the performance of the damper under seismic load is analyzed. The evaluation includes analysis and result comparison of the frame with and without double round steel tube. The finite element analysis software ANSYS is used to find the optimum size of damper and analyze the frames.
