摘　　要：本文建立了平面框架结构体系考虑水平和竖向耦合振动的运动微分方程。运用时程分析法对结构进行了在耦合输入水平和竖向地震波情况下的动力响应计算,并与单维输入竖向地震波的情况进行了对比分析,得到一些有价值的结果。The differential dynamical equation considering coupled vertical and horizontal earthquake was set up in this paper for plane frame structural system. Using time-history analysis method, dynamical responses under the coupled vertical and horitontal earthquake input was calculated. Some valuable results were got after the comparision with that of one direction earthquake input.
