N2 - Most of the modern buildings are constructed using reinforced cement concrete, and these structures commonly have infill walls. Though the mass of infill walls is accounted for in the conventional analysis, the stiffness is usually ignored. One of the reasons for ignoring the stiffness of the infill is the difficulty involved in the modelling. However, such an assumption might not yield realistic results. In this paper, the effect of modelling the infill on the seismic response of a fixed base plane frame structure is considered. Further, an attempt is also made to understand the behaviour of frames under earthquakes of different frequency content. Results show that the base shear response of the fixed base structure is sensitive to the frequency content of the earthquake. However, other responses such as roof displacement and roof acceleration are not much sensitive to the frequency content of the earthquakes.
