摘要
利用ANSYS和ABAQUS两种有限元软件建立了钢管混凝土柱在侧向撞击下力学性能的有限元分析模型,模型得到的计算结果均与已有试验结果的吻合度较高。采用建立的有限元计算模型进行了钢管强度对钢管混凝土在侧向撞击力作用下冲击力时程和侧向位移的影响分析,探明了钢管强度对构件抗撞击性能的影响规律。
By using two finite element software ANSYS and ABAQUS,this paper establishes the FEA model of the mechanical properties of concrete filled steel tube columns under lateral impact. The calculated results of the model are in good agreement with the experimental results. Using the established model,the paper also analyzes the influence of steel tube strength on impact time history and lateral displacement,finding out the rule of the influence of steel tube strength on impact resistance of the component.
