継手長さの異なる山形鋼筋かい接合部に関する研究

Abstract

The joint strength of angle brace with high-tension bolted friction connections has been proposed to evaluate based on the number of bolts or focusing on factors other than the number of bolts. In the study, the ultimate strength is organized in splice length through loading tests and numerical analysis using the finite element method. In addition, it is verified whether the ultimate strengths of angle brace can be grasped from the stress distribution of the angle brace in the axial direction. According to the results of loading tests and analysis, it is shown that when the splice length is equal, ultimate strengths is also approximately the same. It was also found that the ultimate strengths can be grasped from the stress distribution in the axial direction.
