This paper reports on results and findings obtained from a nonlinear finite element analysis (NLFEA) of a prototype prefabricated full-depth precast concrete bridge deck panel system under different level of prestressing force. The NLFEA were validated with experimental results obtained from full-scale...

Laboratory Testing of Precast Bridge Beck Panel Transverse Connections for Use in Accelerated Bridge Construction Precast concrete bridge deck panels have been used for decades to accelerate bridge construction. Cracking of the transverse connection between panels is a... SD Porter 被引量: 2发表: 2009...
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...
The principle of construction bytheincremental launchingmethodis to concrete the deck on the ground in successive segments, located at one or two ends of the bridge. When a segment is completed, it is prestressed to the previously completed part of the structure. Then the whole assembled structur...
s factory generally includes facilities for manufacturing a range of products of similar nature according to the firm’s specialization, frame elements, cladding, bridge beams etc. The equipment is thus often highly mechanized including high-speed batching and distribution of concrete, provision of ...
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 ...
