Abstract
The combination of cable-stiffened two-way reticulated shell and aluminum alloy single-layer reticulated shell forms a new kind of shell structure which combines their advantages. The joint system using in this shell structure is aluminum alloy gusset (AAG) joint. Consider the construction of AAG joint, the effect of shear performance cannot be ignored. In order to study the mechanical performance of AAG joint, FE models considering contact between components were established. The results of analyzing bending and shear properties of the joint were imported into a global model (with the span of 60m and the rise of 10m) via a new joint model with the capacity of producing bending and shear deformation. Global stability analysis of the shell under symmetrical and unsymmetrical loads were carried out. The results indicated that the load distribution had little influence, but the effect of joint rigidity is relatively greater.
