Composite Bridges Built in the Area Influenced by a Mining Subsidence

Composite Bridges Built in the Area Influenced by a Mining Subsidence

Paper in proceedings (conference paper)

Composite bridges built in the araea influenced by the effects of the mining subsidence are described in terms of their static and structural solution and function of the composite deck slab. The bridges are formed by two different static systems: plate girders and trough sections that are composite with transversally post-tensioned deck slab. The girders are erected in progressive cantilevers; the composite deck slab is progressively cast in the traveler moving along the already erected steel structure.
