| 摘 要： | 应用ANSYS参数化程序对组合管桁架结构抗弯承载力进行了非线性分析，计算表明有限元模拟与试验结果吻合较好，验证了有限元模型以及编制APDL命令流的正确性。再应用编制的命令流，分析了混凝土翼缘板板厚、混凝土强度、桁架高跨比、桁架钢材强度、桁架管截面尺寸等因素对组合管桁架抗弯承载力的影响，并对其结果进行了探讨。

| Abstract: | An finite element analysis was made on the ultimate buckling strength in composite tube truss with the ANSYS Parametric Design Language(APDL),the calculation showed the finite element model greatly matched with the tested result,indicating that the model of finite element and the command stream of APDL are correct.The command stream was again applied to analyze the influences of some factors on the ultimate buckling strength in composite tube truss,the factors include the thickness of concrete slab,concrete... |
