Evaluation of Suitability of Dampers in different Soil Condition for Multi Storey Buildings under Seismic Conditions

Abstract

We are living in the age of multi storey building due to fast urban development where everyone want to live in the city centre to avail all comfort and accessibility to all facilities needed for daily to day life which resulted in huge demand of high rise and multi storey buildings. Engineers need to find out the different structural arrangements to provide robust design to withstand the earthquake which are common now a d Now-a-days without compromising the occupants comforts. Earthquake cause heavy deflections of the building even if it is design to withstand the earthquake forces safely which cause great discomfort and fear to the occupants in addition to the damage to the finishes and cladding/glazing of the buildings. I order to eliminate large displacement ill effects without designing the stiff building structure which may greater forces at base in terms of base share, dampers has been introduces in the high rise construction industry. This paper is the outcome of the structural analysis study conducted on 13 storey building models to compare the effects of utilizing dampers on building drifts using E-TABS software. After detailed analysis and comparison using E-TABS software it is concluded that the building with dampers performs better under seismic load conditions than the building without dampers under the same loadings and dampers effectively works to reduce to building drifts under seismic loading conditions.
