A STUDY ON SEISMIC RESPONSES OF REINFORCED CONCRETE (RC) BUILDINGS WITH LATERAL FORCE RESISTING SYSTEMS

Reinforced Concrete (RC) framed buildings are widely used for the construction of multistorey buildings in India. Seismic analysis is not considered for most of the buildings designed. But, it is an effective way of designing a building to consider seismic analysis. Seismic analysis is carried out for high intensity earthquakes for multi-storey buildings. For resisting these very high intensity earthquakes in buildings various types of lateral load resisting systems are adopted. Reinforced concrete (RC) framed building without infill are usually analyzed and designed as bare frames. But infill wall reduces the displacements, time period and base shear in a RC frame and it is essential to study the effect of brick infill in the seismic response of RC frame.3 Provision of shear walls increases the strength and stiffness of the structure and thus affect the seismic behavior of framed structure4 . Shear walls are more resistant to lateral loads in an irregular structure 5 . In the seismic design of buildings, reinforced concrete structural walls, or shear walls, act as major earthquake resisting members6 .
