摘要

The response was studied for a wide range of system parameters with the objectiveof: (1) evaluating the effects of plan-wise distribution of stiffness and strength on the response; (2) investigating how the response is influenced by the system parameters; (3) identifying how structural response is affected by plan-asymmetry and how these effects differ between elastic and inelastic systems; and (4) investigating how well the effects of plan-asymmetry on structural response are represented by torsional provisions in building codes. The inelastic responses are presented of several asymmetric-plan systems: with and without resisting elements along the direction perpendicular to the ground motion, with varying number of resisting elements along the direction of ground motion, with varying levels of overstrength and relative values of strength and stiffness eccentricities, and with eccentricity due to uneven distribution of stiffness and of mass. Plan-wise distribution of stiffness and strength is shown to significantly affect the inelastic response of asymmetric-plan systems.
