Abstract
This paper presents seismic behavior of several buildings with low torsional stiffness. The performance criterion is story drift ratio, as story drift ratio is an appropriate damage index for structural and non-structural elements comparably. Therefore, the safety of structure is defined by mentioned criterion. This study illustrates that the proposed provisions of standard 2800 of Iran for linear equivalent static analysis do not generally satisfy sufficient safety for low torsional stiffness structures. Therefore, linear equivalent static analysis in its present form is inadequate for low torsional stiffness structures.
