| 摘 要： | 本文提出了在基于位移的抗震设计中利用弹塑性反应谱计算等效地震荷载即基底剪力的方法,并结合相应我国抗震规范的弹塑性反应谱对一个四层钢筋混凝土框架进行了基于不同延性及位移需求的等效地震荷载的计算,最后讨论了基于位移的抗震设计与目前抗震规范设计方法之间的联系与区别,并提出了需要进一步研究的问题.

| Abstract: | In this paper,a method of calculating the equivalent earthquake force,e.g.base shear force of the building,in the displacement-based seismic design is presented using elastic and plastic response spectrum.The method is illustrated by a four-story RC frame structure with the varying ductility and displacement demands,combining the elastic-plastic response spectrum of the existing seismic code of China.The paper ends with some discussions about the relation and difference between the displacement-based seismic design and the design specified by the existing seismic code provisions,and some issues need to be further studies are proposed. |

| Keywords: | elastic-plastic response spectrum displacement-based seismic design equivalent earthquake load ductility demand spectrum |
