Based on the nonlinear stability analysis method, the 3D nonlinear finite element model of a composite girder cable-stayed bridge with three pylons is established to research the effect of factors including geometric nonlinearity, material nonlinearity, static wind load, and unbalanced construction load on the structural stability during construction.

Besides, the structural nonlinear stability in different construction schemes and the determination of temporary pier position are also studied.

The nonlinear stability safety factors are calculated to demonstrate the rationality and safety of construction schemes.

The results show that the nonlinear stability safety factors of this bridge during construction meet the design requirement and the minimum value occurs in the maximum double cantilever stage.

Besides, the nonlinear stability of the structure in the side of edge-pylon meets the design requirement in the two construction schemes.

Furthermore, the temporary pier can improve the structure stability, effectively, and the actual position is reasonable.

In addition, the local buckling of steel girder occurs earlier than overall instability under load in some cable tension stages.

Finally, static wind load and the unbalanced construction load should be considered in the stability analysis for the adverse impact.
