The usability of precast spun concrete members of annular cross-sections as pier shafts for road bridges and footbridges is discussed. First and second order load effects for shafts of braced and bracing piers are analysed. The modeling of resisting compressive forces and bending moments of ...
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 concretestructures hold immense potential in the construction industry, not only for their advantages during the construction stage but also due to additional benefits associated with cost reduction and environmental impact. Moreover, researchers emphasize the importance of energy and resource conserv...
simple stack of precast concrete sections tied together with a galvanized rod. I gave the system a try last summer on a small deck to see how easy they were to actually install, and to see if they’re cost effective compared with pier-type footings that have been formed and poured on ...
In the construction of concrete bridges, the lighter dead load of decks can significantly reduce the number or size of substructure members, such as girders, piers and foundations. Although, the arch decks (ADs) ensure superior load carrying capacity and can have longer span length than flat dec...
This proposed connection system provides internal connectors between steel piers and precast bent caps. The internal connection is installed in a circular steel pier in the shape of a cross as shown in Figure 1(a). Figure 1(b) shows precast concrete bent cap with an internal connector. After...
