This paper discusses the design bearing capacity of welded pipe joints in marine and construction engineering under the static axial load. Based on the analysis of the ultimate bearing capacity formula and the main factors affecting its strength in the national standards, the proposed formula for bearing capacity is proposed. The proposed formula and the Japanese, American, European normative formulas calculated values and screening test values are compared statistically. The results show that the proposed formula has a clear concept, simple expression form, convenient calculation of various coefficients, and high statistical precision. Finally, based on the principles of our country’s new specification design, taking into account the domestic material and the welding conditions of the nodes, the proposed formula for the design bearing capacity is proposed.
