Transfer and Development Length of Prestressing Tendons in Full-Scale AASHTO Prestressed Concrete Girders Using Self-Consolidating Concrete [PDF]

open access: yes, 2009
Self-consolidating concrete (SCC) is a highly workable concrete that flows through densely reinforced or complex structural elements under its own weight. The benefits of using SCC include: a) Reducing labor costs by eliminating the need for mechanical

Temperature field characteristics of concrete box girders in rigid-frame bridges based on fine simulation and monitoring

open access: yesCase Studies in Thermal Engineering
The non-uniform temperature distribution in long-span double-box single-cell concrete box girder bridges can lead to reduction in structural bearing capacity and temperature-induced diseases.

Laboratory Testing of Railroad Flatcars for Use as Highway Bridges on Low-Volume Roads to Determine Ultimate Strength and Redundancy [PDF]

open access: yes, 2013
Railroad flatcars (RRFCs) are a convenient option to replace existing deteriorating bridge structures on low-volume roads. They are typically used as the bridge superstructure by placing two or more flatcars side-by-side to achieve the desired bridge ...
