中文摘要：
回传矩阵法自提出以来已被成功应用于平面桁架结构和层状介质的瞬态响应分析中。从编制统一的空间框架结构回传矩阵法动力计算程序的角度出发，给出回传矩阵法列式的统一推导过程，考虑材料阻尼、节点集中质量和弹簧阻尼支撑等因素，将原回传矩阵法推广应用到复杂空间框架结构的自振特性分析中。数值算例表明该方法在求解自振特性时具有计算精度高、求解代价小等优点。
英文摘要：
Reverberation matrix method has been proposed for transient analysis of planar trusses and layered media successfully. This article, aiming at writing a general dynamic analysis program for complex space structures, presents general formulations which include effects of material damping, joint mass, joint spring support and joint damping. Numerical examples are given, indicating that the reverberation matrix method has the advantage of high accuracy and less computational cost.
