Abstract:The roof of sports center in Pi County adopts aluminum alloy single-layer latticed shell structure. The structural selection of the roof was mainly introduced. The static and integral stability analysis of the aluminum alloy single-layer latticed shell was carried out by the finite element software, and the latticed shell and the lower concrete structure were assembled to analyze the influence of the substructure on the mechanism of the latticed shell. At the same time, the bearing capacity and stiffness of the joints were analyzed by solid finite element model. The calculation shows that the aluminum alloy single-layer latticed shell structure is mainly controlled by the overall stability, and the strength and stiffness of the joint can meet the requirements. The analysis results can provide reference for the design of the same kind of structure.

Keywords:aluminum alloy single-layer latticed shell; static design; buckling analysis; integral model; support design
