Seismic studies on energy dissipation device performance for irregular steel structure in different soil conditions using ETABS

Abstract

Abstract Earthquakes are sudden loads that occur and cause low to severe damage to the structure. Based on the intensity of an earthquake, the zones are divided into II, III, IV and V as per IS code 1893:2016(Part-1). Regular, Stiffness Irregular and Mass Irregular G+7 steel building is designed for four zones in ETABS software. Linear Static and Linear Dynamic analyses are performed on all zones for different conditions of soils. In this work, a steel G+7 storeyed structure is developed in ETABS and subjected to seismic loading. For Energy dissipation, the dampers are installed in the building and the analysis process is done. In this research, seismic study is carried out on various models using energy dissipation devices such as fluid viscous damper. The different irregularities in a building in four zones are analyzed with and without using dampers. The study is concluded by comparing displacement and storey shear values for different models.
