摘要According to the three-fork shaped River terrain of the Grand Canyon, a design scheme of three-fork shaped single main cable pedestrian landscape glass suspension bridge is proposed. The three-fork shaped single main cable is suspended on three single column bridge towers, and the sling system is suspended with a three-fork shaped deck stiffening beam with a central ring. Both the three-fork shaped single main cable and the three-fork shaped deck stiffening beam are stable triangular structures, it has good spatial stiffness. Combined with the actual project, the engineering parameters are designed, the Midas finite element analysis model is established, and the static analysis and dynamic modal analysis are carried out to verify the structural rationality of the three-fork single main cable pedestrian suspension bridge.
Abstract：According to the three-fork shaped River terrain of the Grand Canyon, a design scheme of three-fork shaped single main cable pedestrian landscape glass suspension bridge is proposed. The three-fork shaped single main cable is suspended on three single column bridge towers, and the sling system is suspended with a three-fork shaped deck stiffening beam with a central ring. Both the three-fork shaped single main cable and the three-fork shaped deck stiffening beam are stable triangular structures, it has good spatial stiffness. Combined with the actual project, the engineering parameters are designed, the Midas finite element analysis model is established, and the static analysis and dynamic modal analysis are carried out to verify the structural rationality of the three-fork single main cable pedestrian suspension bridge.
