Abstract
Based on the nonlinear theory of cable-stayed bridge, nonlinear effects- cable sag, beam column effect, large displacement are calculated accurately using element geometric stiffness matrix, CR formulation, bar unit, Ernst formula and the catenary equation. Nonlinear analysis is applied on the study of cable force, the stress in main girder, pylon stress and tower deviation of the four towers cable-stayed bridge. The calculation results considering nonlinear effect is compared with which nonlinear effect is not considered under completion state. Results show that the geometric nonlinearity effect on the cable force is 0.09 ~ 1.04%; the effect on cumulative vertical displacement is -5 ~ 5mm; the effect on the lower edge stress of main girder is 0.5 ~ 1.5%; the effects on the higher edge stress of main girder is 0 ~ 0.5%. The effect on the lower edge stress of girder is significantly higher than the upper edge. The effect on the stress of tower is -0.1 ~ 0.1MPa; the effect on horizontal deviation difference at the top of tower is 1.4%~3.1%. Results show that the geometric nonlinearity has a certain effect on the state of bridge, the effects of geometric nonlinearity should be considered in design and construction control calculation.
