Long-span prestressed structures present distinct challenges during tensioning. Their considerable length inherently induces significant tendon friction, resulting in substantial prestress loss. Additionally, prestressing operations within buildings will

Cracking of the End Diaphragm of a Post-tensioned Beam Bridge
In concrete beam bridges, the end diaphragm at the end of the bridge is a common structural component that connects the main beams and transfers the beam loads to the bridge bearings.

Ultrathin AlOxHy interlayers between aluminum films and polymer substrates significantly improve electro‐mechanical properties of flexible thin film systems. By precisely controlling interlayer thickness using atomic layer deposition, this study identifies an optimal interlayer thickness of 5–10 nm that enhances ductility and delays cracking.

Degradable Polyphosphoester (PPE) gradient copolymers (GCPs) are synthesized via one‐pot copolymerization. We show that GCPs self‐assemble into nanostructures like polymersomes, effectively mimicking the behavior of traditional BCPs. The gradient strength is key, with softer gradients favoring micelles.

Nonlinear Models of Reinforced and Post-tensioned Concrete Beams
Commercial finite element software generally includes dedicated numerical models for the nonlinear response of concrete under loading. These models usually include a smeared crack analogy to account for the relatively poor tensile strength of concrete ...

Impregnation Technique Provides Corrosion Protection to Grouted Post-Tensioning Tendons
Thousands of bridge structures rely on grouted post-tensioning (PT) tendons. Problems with grouting techniques and grout materials have resulted in bridges with grout voids, chloride contaminated grout and soft grout.
