Full-Depth Precast Concrete Bridge Deck Panel Systems

Full-Depth Precast Concrete Bridge Deck Panel Systems. Washington, DC: The National Academies Press. doi: 10.17226/23122. The conclu- sion may be unnecessarily conservative as the authors do not believe that the push-off testing is as realistic in mod- eling beam behavior as is the actual beam test, which showed no reduction in capacity due

PDF ABC-UTC Guide for: Full-Depth Precast Concrete (FDPC) Deck

Figure 3.10: Precast Concrete Deck Panel with Integral Barrier [2] A recent project was completed by Iowa State University supported by the Accelerated Bridge Construction University Transportation Center (ABC-UTC) [7]. A detail was developed through static testing for the connection between a deck and a precast barrier, shown in . Figure 3.11.

PDF Second Generation Precast Deck Panel (Nudeck) System

The majority of today's bridge decks are built using cast-in-place concrete construction. This is due to the perceived low initial cost and constructor familiarity with the system. This research report describes the design, details, and construction of an innovative full-depth precast concrete bridge deck system - the Second Generation NUDECK

This test was conducted with the primary focus area being the appraisal of the horizontal shear strength of the slab girder system by the use of different alignments to the shear pocket. The results obtained from the experiment were also compared with the horizontal shear strength predicted by AASHTO and American Concrete Institute interface shear transfer between bridge surfaces and the

Horizontal Shear Transfer for Full-Depth Precast Concrete

"The Effect of Bedding Layer on the Strength of Shear Connection in Full-Depth Precast Deck," Engineering Journal, American Institute of Steel Construction, Vol. 39, pp. 127-135. Shear connection in a steel-concrete composite bridge with a full-depth precast deck is characterized by the material properties of the non

PDF Shear Connections for The Development of A Full-depth

shear connection between the full-depth precast deck and a precast concrete girder via a pocket-haunch-connector system. Push-off tests are performed to investigate the effects of various pre- and post-installed shear connectors, haunch height, surface roughness, grouping effects, and grout composition as compared to cast-in-place specimens. The

What is Spalling Concrete? Their Causes and Repair - The

Their Causes and Repair. Spalling is break away of concrete surface which often extends to the top layers of reinforcing steel. Spalls may be 150 mm or more in diameter and 25mm or more in depth, and the occurrence of smaller spalls also possible as per ACI 302.1R-4. Spalling of concrete affects a broad variety of structures including framed

SHEAR CONNECTORS FOR Scott Walbridge is an Associate

The first use of full-depth precast concrete bridge deck panels occurred in the 1970s at several locations in the United States, however, these bridges were primarily non-composite [1]. Advances were made to precast technology and a decade later transportation departments were using composite designs, realizing the advantages of

Numerical Modelling of Concrete-to-UHPC Bond Strength

Although the bond strength between normal concrete and UHPC has been experimentally investigated by many researchers while using bi-surface, slant shear, push off, and pull-off tests [39,40,41,42,43,44], there is a gap knowledge that is related to the numerical modelling of the interfacial bond strength for repair design and evaluation.
