摘要
在Murray模型的基础上 ,采用VonMises屈服准则 ,推导了在轴向压力影响下的倾斜塑性铰线承载力公式。建立了在弦杆轴向压力影响下 ,直接焊接T型方管节点抗轴压的塑性铰线模型。得出的节点承载力公式与规范 (IIW、欧洲推荐、AWS)采用的经验公式、非线性有限元计算结果及实验结果吻合较好 。
A formula of inclined yield line for the t?type RHS joint under an axial force is proposed in the paper It is based on Von Mises yield criterion to drive the formula of bearing capacity of the joint;the Murray′s model is used in the analysis A detailed discuss is made to compare the result of the proposed formula with other results The comparative results are shown that the result of formula is in good agreement with that of the nonlinear finite element and test data Meanwhile,the result of the formula is also in an agreement with that of other codes It is verified that the formula is feasible
