Abstract:The sudden movement of earth causes damage to or collapse of buildings and other manmade structures. Hence seismic analysis is necessary for a structure. In the present study, an attempt is made to study the difference in structural behaviour of 3- dimensional 4*6 bays, 12 storey basic moment resisting RC frame provided with external and internal shear wall and masonry infill as LLRS. The detailed investigations are carried out for zone V of seismic zone of India as per IS 1893 (part-1):2002, considering primary loads and their combinations.6 models are analysed which consists of basic moment resisting frame with square column and frames with external shear wall and internal shear wall at corners and mid frames and frames with masonry infill as LLRS. The results obtained from the Equivalent static lateral load method are thoroughly investigated for maximum values of joint displacements, support reactions, beam force, forces in truss elements. The results indicate better resistance to lateral loads in the presence of masonry infill provided at centre frame of the building.
