ABSTRACT
For the connection joints between self-locking and unlocking steel structure module elements, the tensile model of the joint is established by ABAQUS finite element software. Through parametric analysis, the stress characteristics of corner parts and plug-ins when the joint is in tension and the influence of plug-in neck width on the tensile bearing capacity of the joint are studied. The results show that the connection joints between self-locking and unlocking steel structure module elements have good bearing capacity; the important factor affecting the bearing capacity of the joint is the plug neck width. Reducing the plug neck width is conducive to improving the yield-bearing capacity of the joint.
