Performance study on T-stub connected semi-rigid joint between rectangular tubular columns and H-shaped steel beams

摘要

This paper investigates the performance of T-stub connected semi-rigid joint of rectangular tubular columns and H-shaped steel beams.The finite element analysis software ABAQUS is used to analyze the nonlinear performance of the joint under monotonic loading.Meanwhile,the dimensions of T-stub,column and beam are considered as analytic parameters to discuss the performance of the joint.The analysis shows that the thickness and the length of T-stub webs,the height of beam section,bolt diameter,shear connector and the preloaded force affect the performance of the joint largely,and the thickness of the steel tube,the thickness and length of T-stub flange,bolt spacing have relatively little influences on the performance of the joint.The research results indicate that this joint is semi-rigid joint.
