Anchorage Zone Design for Pretensioned Bulb-Tee Bridge Girders in Virginia
… of Virginia develop cracks within the anchorage zone region. The lengths and widths of these cracks range from acceptable to poor and in need of repair. Field observations also indicate deeper cross sections, very heavily prestressed sections, and girders with lightweight concrete tend …

Performance and Design of Anchorage Zones for Post-Tensioned Box Girder Bridges
… form of bridge construction. The post-tensioning anchorage zone is the location where very large prestressing forces are applied to the box girder, and then spread into the box section. The spreading of the large compressive forces creates transverse tension forces that must be considered in …

DESIGN & DEVELOPMENT OF HETEROTOPIC TRANSCATHETER TRICUSPID VALVES TO AMELIORATE TRICUSPID REGURGITATION
… tricuspid valve anatomy and the lack of an anchorage zone. Thus, the next best anchorage zone is the vena cava. Placing the valves in the superior and inferior vena cava will prevent the back flow of blood into the venous structures and minimises the detrimental effect of reverse flow. The …

CFRP as Shear and End-Zone Reinforcement for Concrete Bridge Girders
… of CFRP grid needed for reinforcement in the anchorage zone. This thesis concludes that NEFMAC grid is a viable shear design option and presents the initial recommendations for design methods. These methods provide a basis for the design of NEFMAC grid shear reinforcing that could be used as a …

Deterioration and Cracking in Reinforced Concrete Bridges
… does not benefit from support confinement in the anchorage zone of the longitudinal tensile reinforcement. Moreover, leakage of contaminated water often causes corrosion of the internal steel reinforcement and cracking of the concrete cover. Thus, half-joints are particularly vulnerable to bond …
