Seismic Analysis of Multi-Story Building with Underneath Satellite Bus Stop Having Service Soft Story and Moment Transfer Beams

Generally, RC framed high rise structures are designed without regards to structural action of masonry infill walls present. Masonry infill walls are widely used as partitions. They are considered as non- structural elements. RC frame building with open first story is known as soft story, a similar soft story effect can also appear, at intermediate story level if a story used as a service story. The soft story located in the lower part of the high rise building especially the first story is very undesirable as it attracts severely large seismic forces. In satellite bus stops the ground soft story is of double height than the normal buildings and has sufficiently larger spans for movement of buses, so the effect will be more. At the same time, the soft story located in the upper part of the high rise building does not significantly affect the performance compared to the performance of the fully infill frame.
