Reinforced concrete frame buildings have become common form of construction with masonry infills in urban and semi urban areas in the world. The term infilled frame denotes a composite structure formed by the combination of a moment resisting plane frame and infill walls. The infill masonry may be of brick, concrete blocks, or stones. In the current practice of structural design in India infill walls are conside red as non - structural elements and their strength and stiffness contribution are neglected. The effect of infill panels on the response of reinforced concrete frames subjected to seismic action is widely recognized and has been subject of numerous experim ental and analytical investigations over last five decades. The framed building behaves differently as compared to a bare framed building (without any infill) or a fully infilled framed building under lateral load. A bare frame is much less stiffer than a fully infilled frame; it resists the applied lateral load through frame action and shows well - distributed plastic hinges at failure. In this study high rise buildings of regular and irregular geometry with 200 mm cement infill thickness under earthquake zo nes - V with different infill positions are considered so as to evaluate the efficient building frame. These are achieved by comparing the result with different parameter like moment, shear for ce, peak displacement and drift .
