A REVIEW PAPER ON TORSIONAL BEHAVIOR OF ASYMMETRICAL BUILDINGS

Abstract

The structures having discontinuity in their mass, stiffness and geometry, such structure is termed as asymmetric/ irregular structure. At the present scenario there are many buildings which are asymmetric in their plan as well as in elevation. These asymmetry leads to major damage during earthquake than regular buildings. Sometimes irregularities are not avoidable in construction of buildings. However the torsional behavior of asymmetric building during earthquake needs to be studied for appropriate design and better performance of building. Several studies of structural damage during past earthquake conclude that torsion is the most critical factor leading to major damage or complete collapse of a building. The object of the present work is to state a review on the past papers presented on torsional behavior of asymmetrical buildings. So the present work provides a good source of information to understand structural behavior of building with irregularities under strong ground motion.
