为给交通重点目标平时建设中的抗爆设计和战时受打击后的毁伤评估提供技术支持,利用显式动力有限元软件Ansys/LS-DYNA,研究爆炸作用下钢筋混凝土板的毁伤效应。使用Conwep方法计算并加载爆炸荷载,采用分离式共节点方法建立钢筋混凝土板,建立爆炸荷载作用下钢筋混凝土板毁伤模型,并对爆炸作用下钢筋混凝土板的破坏模式进行研究,结合相关试验对仿真模型进行验证,试验数据与仿真结果吻合良好。
In order to provide the technical support for the antiknock design and the damage evaluation after wartime construction in the usual construction of the traffic target, the damage effect of the reinforced concrete slab under explosion was studied by using the explicit dynamic finite element software Ansys / LS-DYNA. Using the method of Conwep to calculate and load the blasting load, a new method of separating the common nodes was used to build the reinforced concrete slab. The damage model of reinforced concrete slabs was established under the action of explosion load. The damage modes of the reinforced concrete slab under blasting were studied. The model is validated and the experimental data agree well with the simulation results.
