SEISMIC ANALYSIS OF MULTI-STOREY R.C. STRUCTURE USING BRACING SYSTEM AND FLOOR DIAPHRAGM
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 2015, Vol 4, Issue 12
Abstract
Earthquakes are natural hazards which cause disasters are mainly caused by damage too or collapse of buildings and other manmade structures. Experience has shown that for new constructions, establishing seismic resistant controls and their implementation is the important safeguard against seismic induced damage. In this study, seismic analysis of multi storey RC building frames have been carried out considering different types of bracing systems. Bracing systems are very efficient in resisting lateral forces. STAAD.Pro software has been used for analysis purpose. Analyses of multi storey RC building frames are carried out in 3 parts I) Building frame without bracing systems diaphragm II) Building frames with Bracing systems and III) Building frame with floor diaphragm. Three different type of bracing systems i.e. X Bracing, K Bracing and V Bracing including bracing core and outer pattern have been considered. Results are collected in terms of maximum moments in beams, axial force, shear force, maximum displacement and storey displacement which are critically analysed to quantify the effects of various parameters. This approach focuses on the arrangement of bracing in a structure and their effectiveness in reducing the lateral displacement ultimately to achieve economy in construction with similar structural frames.
