“…The constitutive relation of aluminum alloy, initially proposed by (Ramberg and Osgood, 1939) and (Steinhardt, 1971), laid the groundwork for exploring the behavior of AAG joints. Bending tests of AAG joints at room temperature conducted by (Guo et al, 2015a; 2015b) and (Liu et al, 2019a) provided valuable insights, identifying failure patterns such as member rupture, local buckling, and block tearing of gusset plates. Building upon experimental findings, (Guo et al, 2016) employed finite element (FE) analysis and theoretical derivation to estimate the bearing capacity of AAG joints.…”

Regarding the damage incurred by aluminum alloy latticed shells under fire loads, a crucial aspect in assessing structural integrity is examining the residual bearing capacity of aluminum alloy gusset (AAG) joints. Consequently, this paper conducted experimental and numerical analyses on the post-fire flexural behavior of AAG joints. Initially, twelve AAG joints underwent post-fire tests, revealing that the failure patterns differed between thin-plate joints (exhibiting block tearing of gusset plates) and thick-plate joints (exhibiting member buckling). Notably, the initial stiffness approximately remained constant, while a trilinear relationship emerged between the ultimate flexural bearing capacity and the maximum post-fire temperature. Subsequently, finite element (FE) analysis was carried out, and the accuracy of FE models was verified by comparing the FE results with the test results. A comprehensive parametric analysis, considering various plate thicknesses, post-fire temperatures, and aluminum alloy brands, was then conducted. Ultimately, employing statistical regression, theoretical equations were formulated to estimate both bending stiffness and bearing capacity for AAG joints after exposure to fire.

“…Shi et al [169] conducted experiments on two-way AAG joints subjected to pure bending and shear loading and they proposed a theoretical model able to accurately capture the mechanical behaviour of these joint systems. Liu et al [170] determined experimentally the flexural behaviour of double-and single-layer AAG joints. Comparisons between the two types of the investigated joints demonstrated the superior structural response of the former.…”

“…In 2018, Guo and others [15,16] studied the failure modes of aluminum alloy joint plates at high temperatures and proposed theoretical formulas that can estimate the bearing capacity and bending stiffness of AAG joints at 300 • C. Since 2019, most domestic researchers have focused on aluminum alloy joints. Liu [17][18][19] proposed a high-temperature reduction factor for the ultimate bearing capacity of Al alloy joints. They combined numerical simulations with experiments to propose an effective method for predicting crack locations.…”

Current research on aluminum alloy gusset joints has neglected the influences of the angle between members and the curvature of the joint plate on joint performance. This study introduces the concept of the planar angle and establishes 16 joint models using ABAQUS finite element software with parameters such as the planar angle, arch angles, joint plate thickness, web thickness, and flange thickness. The load-bearing capacity of the novel aluminum alloy arch gusset joint is theoretically analyzed, and the concepts of strong and weak axes are proposed. The failure modes and significance of different parameters regarding the bearing capacity and initial stiffness of the joint under various parameters are summarized. The results indicate that the planar and arch angles significantly affect the bearing capacity, stiffness, and failure mode of the joint.
