Abstract
Welding the reinforced component on the surface of a steel structure is a common method to reinforce steel structures in practical engineering. Work efficiency is low in actual construction because of continuous welding. Intermittent welding was adopted in this study to address this issue. The axial compression performance of reinforced steel columns in an actual project was studied through experiments and with the numerical method. The influence of different intermittent welding reinforcement schemes on the reinforcement of steel box columns was analyzed. Steel box columns with different weld intervals were placed relatively close because of their failure mechanism. The discontinuous welding reinforcement scheme reduced cost and improved efficiency. A simplified numerical model was established to conduct a parametrical analysis. An improved reinforcement scheme was proposed based on the analyzed results. The improved reinforcement scheme enhanced the load conditions and strength of steel angles.
