REDUCE EARTHQUAKE EFFECTS BY USING DAMPERS AND COMPARING DISPLACEMENT, SHEAR DRIFT RESULTS FOR VARIOUS ZONES

Abstract

The current trend toward buildings of ever increasing heights and the use of lightweight, high strength materials, and advanced construction techniques have led to increasingly flexible and lightlydamped structures. Damper as a new effective system is one which is used in structural engineering.Damper is a passive system that absorbs energy and reduces response of vibration. Dampers are found to be a straight forward effective, cheap and reliable means that for decreasing undesirable vibration of structure caused by seismic or wind excitation. This analysis explores further high structure as tuned mass damper in building system for reducing the seismic response of tall structure. The structural configuration consists of RCC frame and Damper (composite frame). This extra structure is additionally of RCC buildings and its beam and column sizes are smaller than that of building. The effects dampers for seismic vibration management are investigated. The proposed dampers on the floors are placed at the top floor on both the buildings. The behaviour of flexible-base structures with connected TMD, subjected to earthquake arises has been investigated. The impact of Dampers on the seismic response of structure is studied. The response spectrum analysis is carried out to access the parameters such as storey displacement, storey drift. It's seen that Dampers within the style of weak structure at the highest of building reduces the displacement and reduce damage.
