Research on reinforcing method for welded hollow spherical joints
Abstract Spatial structures have been extensively employed in the past decades. Some detrimental conditions, initial defects and mechanical degradation may cause damage to structures during their service period. However, some members and joints can continue being used after a reasonable reinforcement. In this study, a damaged 600-mm-diameter welded hollow spherical joint, which is one of the most common joint forms, is employed as a research object. Experimental and numerical studies are conducted to investigate the compressive bearing capacity of the joint after reinforcement. Based on a comprehensive parametric analysis, impacts of various factors on the reinforcement effect are revealed. This reinforcement method of welded hollow spherical joints provide reference for engineering.

Highlights Tests of bearing capacity of reinforced welded hollow spherical joints were carried out. Numerical studies considering thermal effect are conducted to investigate the compressive bearing capacity of the reinforced joint. The influence of various possible physical parameters on the reinforcement effect is analyzed. The calculation formula of the coefficient of improvement of the bearing capacity was proposed. The test and FEA results verified the rationality of the proposed formulas.
