An Approach to Lessen the Stresses in Flat Slab for Earthquake Zone IV

Abstract

It has been examine from various findings that the stresses generated in the flat slab analysis, its intensity should lessen in order to provide stability to the structure. For this, four cases have been taken viz., simple flat slab providing shear wall at lift area, simple flat slab providing shear wall at lift area and at maximum stress location, flat slab with drop providing shear wall at lift area and flat slab with drop providing shear wall at lift area and at maximum stress location on G+11 multistoried residential building located at seismic Zone 4. Using response spectrum method with the help of analysis and design tool STAAD Pro V8i, to evaluate analysis parameters such as nodal displacement, shear forces in column, compressive and tensile stresses, storey drift, von mis stress along with principle stress values. The prime case is obtained in this work is Building Case B2 in terms of reducing the stress.
