Abstract

Abstract: In the present day scenario, the necessity of more flexible civil engineering structures such as tall buildings and long span bridges is increased and they are subjected to undesirable vibration, deformation and accelerations due to strong earthquakes, blasts, wind, moving loads, machines and large ocean waves. Excessive vibration in structures is an unwanted phenomenon which causes human discomfort, waste of energy, partial collapse of structural parts, transmits unnecessary forces and also poses a threat to structural safety and, sometimes leads to collapse.In order to eliminate the undesirable effects of vibrations in structures, it is necessary to understand the behaviour and response of structural systems subjected to dynamic loads such as earthquake and wind loads. In the last few decades the analysis and design of earthquake resisting tall buildings has gained momentum. Several studies have carried out theoretical and experimental studies on tall structures subjected to wind and earthquake loads. As structure tends to be more sensitive to seismic and wind excited vibrations, this has led the engineers to turn up the implementation of damping devices in structures in order to increase the damping and thus decrease the uncontrolled vibrations and accelerations which cause human discomfort.In the present study, G+4 multistory RC bare framed building are considered for linear time history analysis subjected to four types of time history earthquakes using Staad.ProKeyword: Seismic Behaviour, Earthquake Resistance Building ,Ductile Detailing,G+4 Rc Building,Is 13920-2016
