摘　　要：为有效地进行杆系结构应力波响应分析,基于传统的空间杆系结构回传波射矩阵法,考虑黏滞阻尼、复刚度阻尼及节点集中质量的影响,采用VC++编制通用回传波射矩阵法分析程序.该程序可以计算空间杆系结构在任意动力集中载荷作用下任意位置的动力瞬态响应.针对某刚架结构,比较运用该程序与运用有限元法得到的结果,验证该方法的精确度.To implement the effective analysis of the structural stress wave response for beam structure in space, an analysis program of a universal reverberation-ray matrix method is developed by VC ＋ ＋ based on the traditional reverberation-ray matrix method, considering the influence of viscous damping, complex stiffness damping and the concentrated mass of nodes. By the program, the dynamic transient response at any position of beam structure in space can be obtained under any concentrated dynamic load. For a rigid structure, the comparison of the results obtained by the program and the finite element method validates the accuracy of the method.
