ABSTRACT
Aluminum alloy penetrating (AAP) joint system is a new type of semi-rigid aluminum alloy joint developed by adding a U-shaped connector and a penetrating member to the original Aluminum Alloy Temcor (AAT) joint. For the commonly used aluminum materials in structural engineering, 6061-T6 aluminum alloy, the static out-of-plane bending moment resistance tests of six specimens of the AAP joints are carried out. The failure modes and moment (M)-rotation (Φ) curves of different cover shapes are obtained. Considering the influence of factors such as the contact surface, installation gap and bolt pre-tightening force on the joint, finite element method is used to establish simulation models of AAP joints and AAT joints, and the failure modes and M-Φ curves are obtained. By comparing the static performance of the two joints, the stiffness and bearing capacity of the new AAP joint are significantly better than the traditional AAT joints. The parameter analysis of the rotational resistance performance of AAP joints and AAT joints under bending moment and different axial tension and pressure is carried out. Comparing the rotation performance of the two joints under different axial forces, the axial tension force is a more unfavorable load for the joints, and the AAP joints perform better than the AAT joints after being subjected to the axial tensile load.
