Earthquake is one major reason for the fatal as well as economical loss globally. It needs to be handled carefully so that life hazard and damage can be mitigate. It becomes the responsibility to design the structure considering most stable output against seismic forces. This Book gives detail computational comparison of Buildings with change in Soft Storey ( Floor without Infill walls ) Locations since, soft storey is considered one of the prime reason for structural failure during earthquake. The RCC structure is modeled and analysed computationally for various location of Softstorey and its comparative analysis is shown to reflect the effect of level of soft storey and structures behavior against seismic forces.
