| 摘 要： | 采用有限元分析软件ANSYS/LS-DYNA,建立了不同截面形式的复式钢管混凝土柱有限元模型,并采用后处理软件LS-PREPOST对复式钢管混凝土柱在3种典型工况下的动态响应进行分析。结果表明:由于钢管的存在,复式钢管混凝土柱具有良好的抗爆性能。模拟结果可为复式钢管混凝土的抗爆设计、抗爆加固和结构选型提供一定的参考。

| Abstract: | Based on the finite element analysis software ANSYS/LS-DYNA,it was established some finite element models of multibarrel tube-confined concrete columns at different cross-section form,and was analyzed the dynamic performances of them under three typical blast action by the post-processing software LS-PREPOST.The results showed that multibarrel tube-confined concrete columns had a good performance in anti-explosion.The simulation results could provide some references for anti-explosion design and the reinforcement of multibarrel tube-confined concrete columns and the selection of the structure form. |
