Abstract

A high rise building has to be designed to resist lateral loads due to wind or earthquake. Interior structural system or exteri lateral load resistance to the structure. influence the behaviour of str dimensional analytical models of G+12 storied building regular and irregular buildings and analysed using CSI ETABS software (2015 version) for earthquake zone III in India. The objective of the project is to carry out seismic analysis (RSA) of regular and irregular reinforced concret carry out the ductility based design using IS 13920. Results of this analysis are discussed in terms of story displacements, story drifts, story shear and stiffness. From the results it is concluded that story displacements increases lin the building; maximum storey drift is observed at second floor for irregular structure and at fourth floor for regular structure; maximum storey shear force was observed between ground floor and second floor for regular structure and a irregular structure and the value decreases linearly with height; storey stiffness varies non - linearly for both the structures with maximum values at ground floor
