ESSENCE OF POUNDING GAPS IN SEISMIC ZONE IV AND V WITH & WITHOUT SHEAR WALLS

With the advent of new technologies, design philosophies and smart materials the mitigation techniques presented in civil engineering structures have gradually been reducing the effect caused by natural disasters such as earthquake and cyclones etc. The pounding effects during the earthquakes have significantly reduced with the inception of shear walls in multistorey RC framed buildings. To ascertain the magnitude of mitigation effect with shear wall, G+10 and G+8 storey adjacent RC framed buildings in Seismic Zone IV and Zone V were simulated in ETABS software using Response spectrum analysis. Even though there is a small seismic pounding gap is required for the buildings with shear walls, the seismic code IS 1893(PartI):2016 prescribed very conservative values.
