Abstract:
Taking Ningbo Xiangshan Port Bridge of Zhejiang Province as an example, the differences of the wind loads and structural responses caused by smooth cables, screw thread cables, pitted cable at high and low wind speeds were compared. The results show that the wind load caused by aerodynamic measures is larger than smooth cable in the most cases. The maximum difference among wind loads on different forms of stayed-cable is about 66%, the tower bottom bending moments caused by the wind load of stayed-cable take the proportion of 24% to full-bridge bending moments of the wind load, the mid-span bending moments of main span caused by the wind load of stayed-cable take the proportion of 46.3%, sufficient attention should be paid to the conclusion.
