[摘要]  對空間多平面圓鋼管相貫節(jié)點承載力進行了研究，包括復雜多平面相貫節(jié)點的拆分原則、中外規(guī)范公式對比、多平面相貫節(jié)點承載力折減系數(shù)取值等，最后得出文中提出的復雜多平面相貫節(jié)點的拆分原則是合理的；采用歐洲規(guī)范對相貫節(jié)點進行校核偏安全；提出的多平面相貫節(jié)點承載力折減系數(shù)對武漢火車站工程是適用的。

Abstract:  Bearing capacity of multi-planar tubular joint is studied, including the principle of decomposing the multi-planar joint into planar joint, comparison of the bearing capacity formula of foreign with domestic code and the reduction factor of the multi-planar joint. It is concluded that the principle of decomposing the muti-planar joint into planar joint proposed is reasonable. It shows a tendency to be safe using the formula of Eurocode code to evaluate the bearing capacity of the tubular joints. The reduction factor of the multi-planar joint is suitable for the project.
Keywords:  tubular joint; bearing capacity of the joint; multi-planar
