低速横向冲击下钢管混凝土构件的力学性能研究

PERFORMANCE OF CONCRETE-FILLED STEEL TUBULAR (CFST) MEMBERS UNDER LOW VELOCITY TRANSVERSE IMPACT

  • 摘要: 建立了钢管混凝土构件在低速横向冲击作用下的有限元计算模型,其中考虑了钢材和混凝土的应变率效应以及钢管和混凝土界面的接触关系。与现有试验结果对比,分析结果表明:有限元模拟结果和试验结果吻合较好。之后采用该有限元模型进行了参数分析,讨论了各参数对钢管混凝土在冲击荷载下的力学性能的影响。

     

    Abstract: A finite element analysis (FEA) model is developed to predict the behaviour of concrete-filled steel tubular (CFST) members under a low velocity transverse impact, in which the strain rate effects of steel and concrete components and the interaction between steel and concrete interfaces are considered. The test results are used to verify the accuracy of the model. It is found that it can predict the test results with reasonable accuracy. The influences of key parameters that may influence the impact resistance of the member are investigated.
