Abstract: Reinforced concrete Structures are very common type of construction in India. Analytically while modeling the structure, we design only beams, columns, slabs and footings, where walls are not considered while designing but wall loads are considered on the beams but in practical construction, the infills are placed in the structure. While designing, infills are not considered as structural elements and their influence on the structural response is neglected. Their impact is shown in the global behaviour of RC frames subjected to seismic loads. So it is very important to study the behaviour of infills on the RC bare frames. The presence of infills results in increase in the structural stiffness; it also increases natural frequency of vibration which depends on seismic spectrum. In addition to that, it also decreases the storey drift demands and increases the storey lateral forces. The presence of infills changes the behaviour of reinforced concrete bare frame along the height of the structure and changing the lateral load transfer mechanism. In this study, 3 and 6-storeyed reinforced frames without infill and with infill is considered and evaluated through non-linear analysis. The objective of this paper is to compare various parameters such as Time period, Base shear, Storey drifts, Displacements and to study the performance of the building. Taking the above parameters into consideration, we can compare performance of infill Structures with the structures without infill in seismic zone III.
