5. Other construction methods for prestressed concrete bridges
Other construction methods for prestressed concrete bridges are :
self-supporting hanger construction;
construction in progress.
Self-supporting arch construction consists of building a structure in full spans in an arch suspended from a load-bearing steel structure. This structure is supported, towards the "rear", on the end of the deck already in place and, towards the "front", on a pier (or abutment). Once the concrete of the new span has hardened and been prestressed, the bend is moved to span the next span, using a metal forebay to facilitate docking on a new pier.
A distinction is made between "overhead" self-launching hangers, which carry the formwork by means of hangers, and "underneath" hangers, in which the formwork is attached to the load-bearing...

Standards and norms
Bridge design and dimensioning are governed by French standards transposing European standards (Eurocodes), and may be supplemented by national standards. In seismic zones, the requirements of current national regulations must be taken into account.
