Abstract: The need for upgrading a large number of understrength and functionally obsolete bridges in the United States has been well documented. The purpose of this project was to investigate two schemes for strengthening the ...

Abstract: One significant cause of deterioration of steel bridge structures is the corrosion due to extensive use of deicing salts in winter weather. The investigation presented in this paper focused on the behavior of steel composite ...

Abstract: Each year many prestressed-concrete (P/C) girder bridges are damaged by overheight vehicles or vehicles transporting overheight loads. The effects of this type of loading on P/C bridge behavior was investigated for various ...

Abstract: Due to lack of maintenance, increase in legal loads, and increased traffic volumes, several thousands of deficient bridges in the surface transportation system needed to be rehabilitated or replaced. One potential solution ...

Abstract: In response to problems of corrugated metal pipe (CMP) culvert uplift failure caused by unbalanced inlet hydraulic loading, full-scale field testing and numerical analysis were carried out to develop a rational design ...

Abstract: Increases in legal-load limits as well as lack of maintenance has rendered a large number of bridges in the United States deficient and in need of rehabilitation or strengthening. Many of these bridges are classified as ...

Abstract: This paper presents shakedown and plastic collapse test results for a one-third–scale bridge system. The bridge was a three-span, four-girder composite bridge comprising compact and noncompact sections. Experimental results ...
