Local stress analysis of arch foot of space special-shaped steel arch bridge
The design and calculation of space shaped steel structure arch bridge is complicated.Taking Jinyan Bridge as an example,finite element modeling analysis is carried out on the steel-concrete joint section of arch foot of space shaped steel structure arch bridge.Plate element is used to simulate steel structure,solid element is used to simulate concrete structure,and line element is used to simulate prestressed steel bundle.According to the calculation results of the most unfavorable combination of effects of the overall structure model of the bridge,the structural force of the steel arch rib at the arch foot position is obtained.Through the analysis and calculation of the relevant components of the arch foot,the de-sign idea and construction precautions are proposed,which provides some reference value for the relevant bridge.
