| Abstract: | The article introduces the overall design of the elevated pedestrian crossing in Yunliang Road of Pudong Shanghai.The crossing is a 27 m + 27 m 2-span steel-pipe truss continuous beam bridge.The space finite element program is used to set up the beam unit model for analyzing its bearing.The article understands the stress conditions of every pole according to the bearing result,and optimizes the design of the larger stressed positions.The new constructional measures are used to improve its stress level. |
