Seismic Response of Soft Storey on High Rise Building Frame
Abstract
The modern trend is toward taller and slender high rise structure is also requiring first storey for parking for vehicle or large space. Due to this functional requirement, the first storey has lesser strength and stiffness as compared to upper storey. As per IS: 1893-2002, the soft storey is the one in which the lateral stiffness is less than 70% of that in the storey above or less than 80% of the average lateral stiffeners of the three stories above. So we have analyzed a 20 soft-story high-rise building frame as per Indian standard codes. The building is situated in seismic zone III. For this we have studied displacements, storey drift, inter-storey drift, storey shear etc. Hence from above study, it can be concluded that there is a need of accurate linear modeling and analysis of existing RC building for seismic response.
