Vam Cong Bridge (Wind Resistant Design)
The Vam Cong bridge in Vietnam is a cable-stayed bridge with 450m length of main span and 840m total length. Vam Cong Bridge, the second bridge spanning the Hau River, a tributary of the Mekong River, will connect Lap Vo district of Dong Thap province with Thot Not district of Can Tho city.
The bridge deck is composite edge girder type, with an overall width of 25.8m, carries four lanes of traffic.
The wind tunnel tests and analyses were carried out to investigate the wind-induced behaviors of the bridge during and after construction. The items of tests and analyses are described as follows:
