Evaluation Study of Multi-Storied Frames with "O Grid Bracing System"

Abstract

Researches in various types of bracing systems that can be used in order to reduce he seismic effect, vibrations etc. On the structures are being carried out now-a-days. Various types of bracing systems that are available are X bracings, H bracing etc. Here in my project I am put forwarding a new shape of bracing as “O grid”. Several studies are already in O grids, which already show they provide more desired values comparing to the conventional ones. As a continuation in my project I am finding out which cross section provided for o grid give more desired value and in which all patterns O grid can be arranged in order to give the best value. The analysis for the different cases studies to choose the cross section and performance under different arrangements in multi storied frames is done using ANSYS Workbench 16.1 software. Total deformation is found by both model analysis as well as time historic analysis. Hence this work will offer a good clarity on comparison of deformation, story shear, and frequency.
