Wind Resistance Design for Lizigou Extra-large Bridge During its Construction |
| |
| Abstract: | Wind resistance design was applied to the temporary structures of Lizigou Extra-large Bridge to increase its wind resistance. An analysis was made of dynamic property of main structure of the bridge under typical working conditions, and wind load internal force was calculated. Wind resistant measures were put forward at each construction stages. |
