Abstract
The eccentricity between centre of mass and centre of stiffness produces torsion in asymmetric buildings during earthquakes. In this paper, the inelastic seismic behaviour of asymmetric-plan buildings is studied by using the base shear and torque (BST) surface. BST surface represents all combinations of base shear and torque when applied statically, leading to collapse of the structure. BST surface is a useful tool for the seismic analysis of asymmetrical buildings.
