Comparison of Seismic Response of a Multi-storied Building With and Without Liquid Damper

Abstract

A tuned liquid damper is liquid confined in a container usually placed on top of a building that uses sloshing energy of water to reduce the dynamic response of the system when it is subjected to excitation. Usually, liquid dampers are strictly connected to the main structure. The seismic analysis, also known as pushover analysis, is a subset of structural analysis. It is the calculation of the response of a building structure to earthquakes. It helps in identifying critical members to reach limit states during the earthquake and hence proper attention can be given while designing and detailing. In this study, a comparison of the seismic response of a multi-storied building with and without liquid damper will be studied. Also, a comparison of various liquid dampers will be checked and various parameters like lateral displacement, storey drift, etc., will be studied for the building. Suitability of different liquids was also studied. The software selected for the analysis is SAP2000.
