Seismic Response Control of High Rise Building by using Viscous Damper

Abstract

Seismic response control by using dampers is most cost effective, satisfied the architectural requirement of opening and recent technique to control the vibrations of structures arising due to dynamic loading. The energy induced by earthquake will be absorbed by these devices and the load acted on the main structure of the building will reduce significantly. This study investigates the influence of mechanical control on struct ural systems through strategically applying reliable dampers that can modulate the response of building.In present study, the 3 bay 14-Storied frame structure is compared with the seismic effect of fixed base structure with respect to viscous damper structure. The 14-Storied frame structure is designed with viscous damper by using ETAB software which gave efficient result for RCC frame structure over the fixed base structure. This present study demonstrates how a damper system can be efficient, evaluating its effectiveness for the building in terms of, Time period, storey drift and storey displacement reductions. The storey drift calculated is compared with the minimum requirement of storey drift as per IS 1893:2000. Result shows that viscous damper was effective on the overall seismic response of structure.
