圆管结构相贯节点静力强度的一种实用验算方法

A PRACTICAL METHOD OF CHECKING THE TUBULAR JOINT STATIC STRENGTH

依据弹性薄壳理论,采用有限单元法,对《钢结构设计规范》(GB 50017-2003)中已包括的圆管相贯节点进行了线弹性静力分析,通过对结果的分析比较,提出了一种简便实用的节点强度验算方法,即以主管中面应力的等效应力峰值是否超过材料设计强度与某一安全系数的比值作为衡量的指标,旨在解决规范尚未包括的节点形式的强度验算问题,可供工程设计人员参考。

According to elastic thin shell theory, static and linear analysis of circular tubular joints specified in the current “code for design of steel structures” （GB 50017 - 2003） is carried out by finite element method under axial load. After analyzing the results and comparing them with the code, a convenient and practical method for checking the joint strength is introduced. This method is aimed at solving the problem of checking the strength of joints that are not specified in the current code or the strength of joints that have already been covered in current code but are under both axial load and bending moment load, which be references for engineering designers.
