【摘要】 在总结实际地震震害特点的基础上，结合钢筋混凝土框架三维非线性动力有限元的分析方法，建立了一种能模拟倒塌过程的计算机模型，给出了一种计算机能自动判断局部或整体可动机构的快速算法，并引入计算机可视化、多媒体等最新仿真技术，对钢筋混凝土框架结构的倒塌机理作了研究，仿真实例表明该系统能较好地反映框架的地震倒塌过程．更多还原

【Abstract】 Based on the summary of several earthquake disasters, a computer model is established to simulate collapse course by 3 D nonlinear RC dynamic FEM. A quick algorithm is given for computer to judge structure or mechanism automatically. Also computer visualization and multimedia simulation technology is introduced to generalize RC frame structure’s collapse principle. A simulation example shows that the system can simulate practical collapse course correctly.更多还原
