| 摘 要： | 应用基于离散元原理的颗粒流数值模拟(Particle Flow Code in 2 Dimensions，简称PFC2D)软件，对框架倒塌的全过程进行了数值模拟。模拟结果与框架倒塌的宏观过程吻合，较好地反应出结构在倒塌过程中构件开裂、失效、退出工作、局部倒塌一直到整体倒塌的全过程，并讨论了数值分析中存在的一些难以解决的问题。

| Abstract: | The whole collapse process of concrete frame was simulated with Particle Flow Code in 2 Dimensions(PFC2D) computer program based on the Discrete Element theory. A reasonable agreement with the in-site investigation of concrete frame collapse is reached, and the whole development from column and beam cracking to failure, from part collapse of structure to whole collapse was successfully reflected in the simulation result. Finally, some difficulties in the numerical analysis were put forward and discussed. |
