A precast concrete slab for forming a deck in a bridge superstructure has a chamfer on forward and trailing edges so that adjacent slabs can mate. The slab is reinforced with bars which protrude laterally from the slab on opposite sides and which, in use, extend over support beams. Selected...
Laboratory testing of full-depth precast, prestressed concrete deck panels used in the Boone County IBRC accelerated bridge replacement project. 热度: Shear Strength of Precast Prestressed Concrete Hollow Core Slabs 热度: seismic design and performance of precast concrete segmental ...
Construction ofbridge deckswithprecastprestressed concretebeamsconnected by insitu concretedeck slabs is economical for spans up to 50 m, mainly for structures such as long viaducts, where a large number of beams is required. In the case of in situ concrete construction, the use ofclassical scaff...
A pier and beam bridge structure is formed essentially entirely from steel reinforced, precast concrete elements including elongated, hollow tubular pier members, pier collars, pier base and cap beams, deck beams, deck slabs and side railing members. In forming the support pier structures, the pier...
As the name implies, the half slab is only a half-precast slab, which requires additional reinforcement and concrete topping in-situ. The half slabs need underneath support before topping pouring. Prefabricated half or filigran slabs – as they are sometimes called according to the registered ...

The launch of this type of bridge involves the consideration of many concrete characteristics, with reference to all the concrete properties evolving overtime owing to the high time dependence of the static behavior of the entire structure. The evolution of material parameters, such as elastic ...

For the construction of composite steel-concrete decks of cable-stayed bridges, methods of erection and analysis have to be applied that, upon completion of the deck, accurately yield the prescribed dead load configuration of the deck regarding geometry and forces. During deck erection, no unwanted...
Subsequent to the prestressing of the deck structure and the beams, the bridge deck structure is connected to the beams by a concrete layer cast in situ in the gap between the bottom face of the precast deck slabs and the top face of the prestressed beams. The concrete is preferably of ...
