摘要

摘要: 考虑多种因素对大直径薄壁钢管受弯构件稳定承载力的影响,采用非线性有限元方法对大直径薄壁钢管受弯构件的受力性能进行综合分析。通过分析及参照相关规范,提出大直径薄壁钢管构件受弯构件稳定承载力的建议计算公式。

Abstract: The forced behavior of large sized thin walled tubes members subjected to bending is analyzed by nonlinear finite element.The influence of several factors on stability capacity of these members subjected to bending is taken into account. Thus according to correlative design standard of steel structures, and on the basis of numerical results by the F.E. methods, the calculation formulas of the stability bearing capacity are presented for the members subjected to bending.
