| 摘 要： | 将空间框架简化为平面框架,采用平面梁模型,建立结构自由振动的微分方程,采用静力凝聚法消去主副自由度之间的耦合关系,得到平面框架结构体系考虑水平和竖向耦合自由振动的振型和频率。运用时程分析法对结构进行了动力响应计算,得到了与仅考虑水平或竖向地震输入结构不同的地震响应。

| Abstract: | By simplifying the space frame to plane frame,and applying with plane beam model,the differential equation of free vibration was established.The using of static condensation method eliminated the coupling of the horizontal and vertical displacements and the rotational displacements.Then,the frequency and the mode of free vibration are given which coupling with the horizontal and vertical vibration.Analyzing with the step by step integral method,the structure dynamic response was achieved,which subjected to both horizontal and vertical seismic excitation,and is different from the separate excitation. |
