Analysis of Multi Storey Building for Different Earth Zones using E-TABS




Multi Storey Building, Earth Zones


In general, for the design of tall buildings, both wind as well as earthquake loads needs to be considered. Governing criteria for carrying out analysis for earthquake loads and wind loads are different. As per IS 1893(part 1):2002 and IS 875(Part 3):1987, when earthquake and wind interacts with a building, both positive and negative pressures occur simultaneously, the building must have sufficient strength to resist the applied loads from these pressures to prevent earthquake and wind induced building failure. Seismic Zonation may be termed as the geographic delineation of areas having different potentials for hazardous effects from future earthquakes. The term Zoning implies that the parameter or parameters that characterize the hazard have a constant value in each zone. We obtain a rather simplified representation of the hazard, which in reality has continuous variation. A seismic zone is a region in which the rate of seismic activity remains fairly consistent. A proper way of presentation of vulnerability versus earthquake intensity is to develop vulnerability functions such as those grossly developed for various building types under the earthquake intensities. An attempt has been made to check the performance of RC frame irregular building with shear walls for Earthquake loads in different zones in India. Dynamic analysis like response spectrum method is carried out to compare the results. Totally four different models of 12 storey with shear wall are considered for the analysis using ETABS software. Storey drift, storey shear and lateral storey displacement results are compared.
