This information can be a guide for bridge designers to design and detail curved concrete bridges considering the advantages of new system.^Musa AlawnehAlawneh, M. 2013. Curved precast prestressed concrete girder bridges (Doctoral dissertation, The University of Nebraska-Lincoln)....
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...
A precast concrete bridge and headwall assembly includes a precast concrete bridge unit including a top wall connecting opposite side walls, and a precast concrete headwall having a bottom surface engaged on the top wall of the bridge unit and a series of earth anchors at laterally spaced interval...
Precast Concrete Bridge Column-Footing Connections with Recessed Grouted Splice Sleeve Connectors Connections between precast components in accelerated bridge construction (ABC) play an important role in the overall seismic performance of reinforced con...

Precast Concrete Manufacturer Metromont to Acquire Shockey Precast Group In order to help ensure the contractor's success, Oldcastle Precast was required to assemble all precast concrete components for each bridge at the precast plant. Deep Creek Canyon Bridge Replacement Project Selected as Finalist ...
The seismic behavior of the proposed precast segmental unbonded posttensioned concrete bridge columns for use in regions of high seismicity was investigated experimentally. Posttensioning tendons were placed in the hollow core of the columns and left unbonded with the surrounding concrete to decrease prest...
aconstruction of precast of bridge superstructure normally progresses at rapid rate once the once erection process begins.the erection of precast concrete segments normally does not commence .however .until such time as a large number of segments have been precast and stockpiled because the erection ...
Precast concretesheeting: It has been used as retaining walls, wing walls, and components of the bridgeabutment. Due toprecast construction, there are many advantages such site impacts are reduced and forming and curing times are eliminated. Construction of these types of walls requires detailed geo...
A simplified full-depth precast concrete deck panel system for accelerating bridge construction(ABC) is introduced and a finite element analysis(FEA) is conducted to investigate the static and dynamic responses of this conceptual deck system. The FEA results are compared to those of the traditional ...
