TRANSPORTATION RESEARCH RECORD 1180 7 Bridge Strengthening with Epoxy Bonded Steel Plates DoNITA K. EBERLINE, F. WAYNE KLAIBER, AND KENNETH DUNKER Epoxy-bonded steel plates have been used to strengthen or repair concrete bridges In many countries around the world. Because most of the Information pertaining to this subject bas
DESIGN OF LONGITUDINAL DECK SUPERSTRUCTURESbridge width. Longitudinal deck bridges provide a low profile that makes factured in any length subject to local pressure treating and transportation restrictions. Deck thicknesses of 5-1/8, 6-3/4, 8-3/4, and 10-3/4 inches for ments in horizontal shear. Unglued edge joints may also be used, but the

the edges of the concrete deck from vehicle loads, seal the joint openings, and accommodate concrete deck movements that are produced by temperature changes and creep and shrinkage of concrete. Although the joints are among the smallest components in a bridge structure, the integrity of the whole structure is affected when the joints fail.
SOILVISION - Geotechnical Software Bentley Systems1D/ 2D/ 3D finite element analysis software focused on environmental modeling, including coupled groundwater seepage, contaminant transport, freeze/thaw, and pore-air flow modeling. Software includes fully automatic mesh generation and mesh refinement. Rigorous calculation of actual evaporation by the Wilson method included.
Weathering steel - SteelConstructionfoWeathering steel is a high strength low alloy steel that was originally developed by United States Steel in the 1930s to resist corrosion and abrasion in their ore wagons. It was given the trade name Cor-ten, and was first used in construction on the John Deere World Headquarters building in
tested to evaluate the horizontal shear strength between the precast panel and the cast-in-place portion of the bridge deck. Presently, the Indiana Department of Transportation requires a minimum of 20 shear connectors regardless of panel dimensions. The shear connectors are placed across a broom finished deck panel surface.
