A practical earthquake damage evaluation method for multistory shear-type buildings with eccentricity is introduced based on linear and nonlinear dynamic analyses using one-and two-story building models simultaneously subjected to strong earthquake ground motions in the x-and y-directions. Damage concentration is evaluated considering shear and torsional strength capacity and the corresponding shear force and torsional moment acting in each direction of each story in the building. Nonlinear response analyses of one-story systems with plan asymmetry and varying parameters such as uncoupled lateral period, eccentricity ratio, uncoupled frequency ratio and force deformation characteristics of lateral force resisting elements are carried out and compared with those of corresponding one-story symmetrical systems. Nonlinear responses of two-story asymmetrical building models are also compared with corresponding two-story symmetrical models considering damage concentration.

介绍了一种实用的偏心多层剪力型建筑震害评估方法，该方法基于线性和非线性动力分析，使用一层和两层建筑模型同时承受 x 和 y 方向的强地震地面运动。损伤集中度的评估考虑了剪切和扭转强度能力以及作用在建筑物每层每个方向上的相应剪切力和扭矩。对平面不对称、非耦合横向周期、偏心比、非耦合频率比以及抗侧力元件受力变形特性等参数变化的一层系统进行了非线性响应分析，并与相应的一层对称系统进行了比较。还将两层不对称建筑模型的非线性响应与考虑损伤集中的相应两层对称模型进行了比较。
