STRUCTURAL RESPONSE OF SOFT STORY-HIGH RISE BUILDINGS UNDER DIFFERENT SHEAR WALL LOCATION

Severe structural damage suffered by several modern buildings during recent earthquakes illustrates the importance of avoiding sudden changes in Lateral stiffness and strength. While damage and collapse due to soft story are most often observed in buildings. The lower level containing the concrete columns behaved as a soft story in that the columns were unable to provide adequate shear resistance during the earthquake. Usually the most economical way to eliminate such failure in a building is by adding shear wall to soft stories. Shear walls are one of the most efficient lateral force resisting elements in high rise buildings. So, in this paper occurring of soft story at the lower level of high rise buildings subjected to earthquake has been studied. Also has been tried to investigate on adding of shear wall in various arrangements to structure in order to reduce soft story effect on seismic response of building. This will help in minimizing the impending damages and catastrophes.
