Finite element analysis of axial capacity of CHS brace-H-section steel chord T-joints
摘要
Abstract
A finite element model on CHS brace-H-section steel chord T-joints was generated by Abaqus and validated by comparing the ultimate capacity, deformation process and failure mode with experimental results. The result showed that under the effect of axial pressure, elephant-foot buckling and local buckling occur at the root of brace, and flange buckling occurs at chord; in engineering it should be avoided that the thickness of brace is relatively smaller than chord, or joints should be strengthened; CHS brace-H-sec-tion steel chord T-joints has strong plastic deformation capacity from being yield.关键词
