In view of many limitations in evaluating elasto-plastic deformations of structures by using elastic response spectrum in aseismatic design code for buildings,this paper proposes that elasto-plastic responses of structures under the action of exceptionally serious earthquakes are directly calculated by applying elasto-plastic response spectrum.
由于当采用抗震规范中的弹性反应谱估算结构弹塑性变形时有许多局限性,该文提出了在抗震设计中直接使用弹塑性反应谱计算在罕遇地震作用下结构的弹塑性反应。
