摘　　要：采用ANSYS/LS-DYNA有限元程序对剪力墙结构原地坍塌爆破拆除过程进行模拟。在建模过程中,用杆系单元代替实体单元,将钢筋混凝土看作是单质均匀材料,采用约束混凝土材料本构关系和塑性应变破坏准则,最终模拟的结果与实际情况比较接近。The process of collapse in situation of shear-wall structure due to blasting demolition was simulated in this paper with ANSYS/LS-DYNA. During the course of modeling, pole unit was used to replace entity unit, rein-forced concrete was treated as single uniform material, constitutive relation of confined concrete and plasticity strain fail criteria was adopted, the final result of simulation was relatively close to actual conditions.
