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.
