The cable-stayed-suspension hybrid bridge is a cooperative system of the cable-stayed bridge and suspension bridge. It takes the advantages of each and also makes up for some deficiencies of the two bridge structures, and therefore has better spanning capacity. By analyzing a cable-stayed-suspension hybrid bridge with main span of 1400 m, effects of design parameters including the cable sag to span ratio, the suspension to span ratio, the side span length, the layout of stay cable planes and the subsidiary piers in side spans etc on the wind stability are investigated. Utilizing 3D nonlinear aerostatic and aerodynamic analysis, and based on the wind stability, the optimal values of these design parameters are determined.
