摘　　要：将求解结构瞬态响应的回传波射矩阵法扩展到非对称层合梁框架结构动力响应的计算.求解了层合悬臂梁在自由端脉冲荷载作用下的瞬态速度响应,与有限元法的计算结果进行了比较.并且,求解了一个9杆层合梁框架在半正弦波力脉冲作用下的应变瞬态响应,检验了节点处力矩的平衡,分析了应变响应随层合梁轴向-弯曲耦合刚度变化的规律.The method of reverberation-ray matrix （MRRM） for solving the transient response of structures was extended to the dynamic analysis of composite frames made up of asymmetric laminated beams. The velocity responses of a cantilever laminated beam under pulse load at the tip were solved and compared with that of finite element method. And, the strain responses of a 9-bar laminated frame subjected to a half sin pulse force were analyzed and the equilibrium of moments at a joint was checked and the effect of the coupling stiffness of laminated beam on strain response was illustrated.
