ABSTRACT
Countries like India, the Reinforced concrete frames with masonry infill walls are common in practice, where the region is prone to seismic activity. Generally the masonry infill walls are treated as nonstructural element in structural analysis and only the contribution of its mass is considered and it’s structural properties like strength and stiffness is generally not considered. The structures in high seismic areas are greatly vulnerable to severe damages. Apart from the gravity load structure has to withstand to lateral load which may develop high stresses. Now day’s reinforced concrete frames are most common in building construction practice around the globe. The vertical gap in reinforced concrete frames i.e. created by the columns and beams are generally filled in by brick or masonry and it is referred as brick infill wall or panels. The main objective of this study is to study seismic resistance of RCC frames for G+8 story building with infill walls by using ETABS software in different seismic zones. The comparison was made between story drift, story shear, bending moment, building torsion between building with and without infill walls.

Key words: infill walls, reinforced concrete frames, RCC frames, ETABS software.
