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 …

Spannbetonfertigteile mit teilweiser Vorspannung aus hochfestem Beton
… of prestressing steel in the transmission zone of prestress, in the area of cracks and in the anchorage zone are presented. In order to investigate the behaviour of prestressed and precast members made of HSC a series of pull-out tests, tests for the introduction of prestressing forces as …

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 …

Zum Verbundverhalten von Spannstahl mit sofortigem Verbund unter Betriebsbeanspruchung
… the bond behavior of prestressing strands in the anchorage zone is described. Based on a database covering approximately 400 test results a non-linear approach is presented to describe the bond capacity of strands considering the concrete strength. The influence of cyclic loading on the bond …

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 …
