Seismic response of high-rise building with the effect of soft storey on various levels

Abstract

The high rise building mainly composed of open ground storey meant for car parking, reception lobbies and remaining floors with brick infill walls for occupancy. Due to congested population and high volume of vehicles, parking is a major constraint for the users. To manage the parking space in buildings, ground storey is usually allocated for parking facilities without in-filled masonry walls. The commercial buildings offer parking facilities at intermediate storey levels also due to space constraint. In this study, seismic analysis on building frames with soft storey effect on various levels considering G + 5 building model. The three dimensional building is modelled and analysed using STAAD PRO v8i software. The parameters involved for this study is floor height, and column stiffness. The results were attained based on variations of base shear, storey drift, storey displacement, mode shape, and frequency.
