Abstract

Generally RC framed high rise building structures are designed neglecting the effect of masonary infill walls. Whereas the masonary infill walls are used for partition. The masonary infill walls are treated as non-structural elements. RC frame structures having open first storey is known as soft storey. The intermediate soft storey is such an element where it is left open as service soft storey without infill. As a result the soft storey located at the lower part of high rise building experience severe seismic forces being acting on them. In satellite bus stop where bottom soft storey height is more than double height, will experience more undesirable impact by the seismic forces. Meanwhile the soft storey located in the upper part of high rise building does not significantly affect the overall performance compared to the performance of the fully infill frame. Due to the complexity and lack of knowledge in performing the P-delta analysis, Civil designing engineers end up in performing only Linear static analysis which may eventually lead to catastrophic consequences, leading to the collapse of the building . This analysis is performed to discuss the importance of P-delta effect in RC structures.
