Abstract:

Now a day’s in reinforced-concrete framed structure walls are not continued in the ground storey for the requirement of parking or for commercial space and also the height of the ground storey is increased for the head room requirement. Such buildings are called soft storey buildings. Due to lack of spaces, increasing parking demands and functional requirement, construction of soft storey building is increasing day by day. Such arrangement of parking and shopping space without infill walls and increased height causes stiffness irregularities in the building. The sudden reduction in lateral stiffness and mass in the ground storey results in higher stresses in the ground storey columns under seismic loading. Hence the building is totally collapsed due to soft storey effect during earthquake. Seismic performance of these buildings can be increased by strengthening techniques. A review regarding its collapse behaviour and strengthening techniques is summarized in this paper.
