Seismic Analysis of Multi Storied Building in Various Zones for Different Types of Soils

Abstract

The major challenge faced by any structural engineer around the world is to design a structure which is resistant to lateral forces. Because an earthquake with smaller intensity can result in severe damages to structures, cause death injuries and economic loss if not designed by considering earthquake forces. It is not possible to stop the earthquakes, so design of effective and efficient earthquake resistant building plays key role in design of structures. In this project, 5 models of G+10 storied buildings with one normal plan (Rectangular shape) and left over are irregular plans (C, H, Hollow Rectangle and M5 shapes) will be taken. Plinth area for each model is same but there is change in geometry. The analysis is carried out by considering different seismic zones (namely II, III, IV and V) with three types of soils namely soft, medium and hard for each zone separately using ETABS. Finally, the behavior of these models is assessed by comparing the results obtained for each model. The results like storey drift, lateral displacements, base shear, etc., are considered.
