摘要
鉴于大直径钢管在各种类型的建筑物或构筑物得到广泛应用,采用非线性有限元法研究大直径钢管构件在轴向压力作用下的受力性能,分析多种因素对钢管极限承载力的影响。通过对所选算例的计算分析,得出几种因素对构件承载力的影响趋势。
In view of the wide application of large sized steel tubes in various structures, the performance of steel tube under the axial force is analyzed by nonlinear finite element in this paper. The influence of several factors on carrying capacity is taken into account. The influenced direction of these factors on ultimate carrying capacity is acquired and the basis is provided for the future analysis by the selected example.
