摘要
Abstract
The differences of the load-bearing state and the intensity were considered between steel and concrete while a structure collapsing. A common node separate model was adopted to simulate the collapse process of a reinforced concrete structure by using the finite element analysis software AN-SYS/LS-DYNA. A series of analysis were carried out for the failure processes of the steel and concrete elements inside and outside the steel-reinforced concrete support pillars. And the simulated results were compared with the actual blasting results. It is shown that the common node separate model can describe the load failure differences between steel and concrete in the collapse process of the reinforced concrete structures. And it is feasible that the common node separate model is used to simulate the collapse process of the reinforced concrete structures.关键词
