Refinement of the Inverted T-Beam Bridge System for Virginia
The inverted T-beam bridge system is a bridge construction technique that follows accelerated bridge construction processes. The system was discovered in France and first adopted in the U.S. by the Minnesota Department of Transportation. In 2012 the system was modified and adopted by Virginia, with …

Transverse Sub-Assemblage Testing of the Inverted-T Bridge System
The inverted-T bridge system is a rapid bridge construction technique that consists of precast inverted-T girders placed adjacent to one another and covered with a cast-in-place deck. This system was first implemented in the U.S. by the Minnesota Department of Transportation (Mn/DOT). This research …

Recommendations for Surface Treatment for Virginia Inverted T-Beam Bridge System
… treatment methods for use in the Virginia Inverted T-Beam bridge system. The specific system consists of precast beams with thin bottom flanges placed next to one another, with a cast-in-place slab on top. Previous research has shown that the strength of this system after cyclic loading is …

Seismic performance of an I-girder to inverted-T bent cap bridge connection
… overall moment capacity of precast I-girder to inverted-T bent cap bridge connections for seismic applications. The current design practice, as outlined by Caltrans' Seismic Design Criteria, assumes that the connection between the precast I-girders and the inverted-T bent cap will degrade in a …

Investigation of Concrete Mixtures to Reduce Differential Shrinkage Cracking in Inverted T Beam System
The inverted T-beam system provides an accelerated bridge construction alternative. The system consists of adjacent precast inverted T-beams finished with a cast-in-place concrete topping. The system offers enhanced performance against reflective cracking and reduces the likelihood of cracking due …

Midpoint estimation applied to the vertical-horizontal illusion
… or figure presented below the line), uncued, and inverted T conditions. Subject's mean estimates were near the geometric midpoint in the two cued conditions, and significantly above the midpoint in the uncued and inverted T conditions. Mean estimates in the inverted T conditions were significantly …

Development of a Composite Concrete Bridge System for Short-to-Medium-Span Bridges
The inverted T-beam bridge system provides an accelerated bridge construction alternative for short-to-medium-span bridges. The system consists of adjacent precast inverted T-beams finished with a cast-in-place concrete topping. The system offers enhanced performance against reflective cracking, …

Behavior of advanced innovative materials for improved long-term bridge performance
… for the girders above deck (L-beams and inverted T-beams). In order to address such issue, thermal gradient distribution and profile of L-beams and inverted T-beams are proposed"--Abstract, page iv.</p>

Non-Contact Lap Splices in Dissimilar Concretes
… box beam bridges and in the construction of inverted T-beam systems, among others. It is vital to understand whether the same mechanisms are present across a cold joint with two different types of concrete as are present in traditional non-contact lap splices. In this research, eight T-beam …

Response of Pile-Supported T-Walls to Fill Loading and Flood Loading Based on Physical Model Studies and Numerical Analyses
… are concrete floodwalls that are shaped like an inverted "T" and supported by batter piles, are commonly used by the United States Army Corps of Engineers (USACE) to protect low-lying portions of New Orleans and other areas. The design of a T-wall in southern Louisiana is complex, as the …
