Inelastic Bridge Rating Procedures for Steel-Girder Bridges
Current bridge rating procedures for steel beam and girder bridges ignore the ability of the structure to redistribute forces both longitudinally and laterally. When rating steel bridges...
Steel Alternates for the Hoover Dam Bridge
As input to the Environmental Impact Statement studies of appropriate long span bridges were performed for three alternate corridors across the Colorado River near Hoover Dam. Details...
Influence of Diaphragms on the Overall Performance of Bridges
Field data collected during vehicular loading has been used to evaluate the performance of diaphragms in composite steel plate girder bridges. This has included comparisons with finite...
Physical Testing of Two R/C Skewed Slab Bridges with Integral Wall Abutments
Two one-third scale models of an existing reinforced concrete skewed slab bridge with integral wall abutments were tested statically to failure. Typically, these bridges are designed using...
Bonded Polyester Concrete Overlays Used in California
Bonded polyester concrete overlays have been very successful in California in restoring and preserving bridge decks from damage by road salts. The polyester concrete system has been employed...
NDE of Steel Bridges by Acoustic Emission
