Precast concreteoffers many advantages, including a reduction of the construction period, cost efficiency, high-quality control, fast and accurate erection of members, and environmental protection. Despite the aforementioned advantages of the precast concrete members, the conventional precast members may sho...
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...
By producing precast concrete in a controlled environment (typically referred to as a precast plant), the precast concrete is afforded the opportunity to properly cure and be closely monitored by plant employees. Utilizing a Precast Concrete system offers many potential advantages over site casting of...
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...
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...
