COMPARISON OF DIFFERENT APPROACHES OF ANALYSIS IN REINFORCED CONCRETE FRAMED BUILDING

Abstract

Reinforced concrete (RC) buildings are constructed first as a framed structure. After building frame is constructed the walls also known as infill walls are constructed. These infill walls are not usually taken in analyzing the structure. But these infill walls also give contribution to the overall stiffness of the building. Reinforced concrete (RC) framed buildings with infill walls are usually analysed and designed as bare frames, without considering the strength and stiffness contribution of the infills. However, during earthquakes, these infill walls contribute to the response of the structure and the behavior of infilled framed building is different from the predicted for bare frame structures. The effects of nonstructural masonry infills can modify the seismic behavior of framed buildings to a large extent. The panels can significantly increase the global stiffness and strength of the structure and consequently change the base shear imposed on the building in a seismic ev...
