Time History analysis of the buildings on sloping ground

Abstract

Lets of Previous studies deals with proper planning and construction practices of multi-storeyed buildings on sloping ground. However, in normal design practice the designers generally ignore the effect of sloping ground on the structural behavior of the building. It is very important to consider earthquake effect and design earthquake resistant buildings from the safety point of view. Shear wall is one of the most commonly used lateral load resisting system in the buildings for its better seismic performance. They provide additional strength and stiffness to buildings in the direction of their orientation, which significantly reduces lateral sway of the building. The seismic analysis of a G+4 storey RCC building on varying slope angles i.e., 7.5⁰, 15⁰ and 30⁰ is studied . The seismic forces are considered as per IS: 1893?2002. Lateral load resisting element, shear wall of 150 mm thick is provided. The analysis is carried out to evaluate the effect of sloping ground on structural forces. The free vibration properties like frequency, Modal mass participation ratio, the base reaction and also axial force, bending moment, shear force in columns
