Study of High Rise Structure with Soft Storey at Different Level by Considering Slab as Shell and Membrane

Abstract

The effect of Infill's are often neglected because of the hurry in construction of the skeleton members. Even though the analytical and experimental studies on response of infilled frame have taken place from 1950, they have less considered the involvement of infill in the structural behaviour. The collapse mechanism is being changed if the involvement of infill's walls is considered, and providing soft storey at different level changes the behaviour of building. The consideration of slab as a membrane and slab as thin shell is also taken into account and what effect it has to the behaviour of building is discussed. Dynamic analysis of a 25 storey L shaped building is carried out. Behaviour of slab as membrane and thin shell is evaluated by response spectrum method.
