SEISMIC EVALUATION OF SOFT STOREY BUILDING CONSIDERING ONE BY ONE FLOOR AS A SOFT STOREY

With the advancement in field of high rise construction, various types of frame arrangements have been emerged. Le Corbuiser popularly known as LC was one of the pioneers of, what is now called five points of modern architecture. Hence, he deviced the concept of soft storey, in which stiffness is altered, along with storey height to achieve an asthetic view. The present study is an attempt to analyse soft storey considering one by one floor as a soft storey. The total cases studied are 7. Seismic zone II is considered in the analysis. To analyse soft storey building STAAD.Pro software used. Results are analysed in terms of bending moments, shear forces and nodal displacements. Graphical outputs are also generated
