BRIDGE CONSTRUCTION PRACTICES USING INCREMENTAL

bridge is 2,110 ft. long with a main span of 330 ft. This bridge was launched in two trains, one from each side of the river. Closure of the bridge was accomplished at mid-span of the main span. This method of construction can be applied to bridges made of either steel or concrete materials. The vast majority of concrete bridges built by the

Structural Analysis of Incrementally Launched Bridge

Incremental launched prestressed concrete bridges are built in segments in a casting bed and the finished segments are pushed out of the casting bed to leave space for the construction of subsequent segments. Special knowledge and a high degree of temporary works integration are required in order to successfully design an incremental launch bridge.
