Abstract:Based on the folded plate truss roof of  Belong Lake Athletic Center, compared with the unidirectional fold\|shaped grid, the mechanical performance and working mechanism of the folded plate truss were analyzed theoretically. It is pointed out that the node design is the key to the truss design. The design and calculation of the joints were carried out in combination with the project, and the safety and rationality of the folded plate truss were demonstrated, which provides reference and help for the design and analysis of other similar projects.

Keywords:folded plate truss；  rigid node；  stability analysis
