A Comparative Analysis of Behaviour of Multi-Storied Regular and Irregular Buildings

The current version of the IS: 1893-2016 requires that practically all multi storied buildings be analyzed as three dimensional systems. Buildings may be considered as Regular and Irregular on plain suraface, in mass and stiffness along storey of the buildings. Most of the hilly regions of India are highly seismic. Inthis study, 3D analytical model of G+14 storied buildings have been generated for Regular and Irregular building models and analyzed using structural analysis tool ETABS software. Mass and stiffness are two basic parameters to evaluate the Static analysis of a structural system. Multi storied buildings are behaved differently depending upon the various parameters like mass stiffness distribution, foundation types and soil conditions. In 2001 Bhuj earthquake in Gujrat, India demonstrated the damage and collapse of the buildings due to the irregularities in structural stiffness and floor mass. This Project is concerned with the effects of various vertical irregularities on the seismic response of a structure. The objective of the project is to carry out Regular and Irregular RC building frames by Dynamic Analysis Method.
