Abstract
Inelastic response of one-story building systems with eccentricity is investigated based on linear static and nonlinear dynamic analyses using asymmetric-plan systems simultaneously subjected to strong earthquake ground motions in the x- and y-directions. Inelastic story drift ratios in the x- and y-directions are evaluated considering shear and torsional strength capacity and the corresponding shear force and torsional moment acting in each direction of asymmetric-plan system. Response analysis of one-story systems with one-axis plan asymmetry and varying parameters such as uncoupled lateral vibration period, torsion-to-lateral frequency ratio, rigidity and strength eccentricities, and shear and torsional strength capacity ratio is carried out and compared with those of corresponding one-story symmetric systems. In addition, inelastic response of one-story building systems with two-axes eccentricity including a L-shape asymmetric-plan system is also investigated.
