UNDERSTANDING BRIDGE DETERIORATION

The Texas Transportation Institute is attempting to study the effects of repeated heavy loads on highway bridges to clarify the most probable locations and nature of damage due to overloads and the effects of this damage on bridge service life in order to improve efficiency of bridge maintenance and design decisions. The research is reported in Research Report 462-1F which includes a literature study of field study, and a finite element numerical study to determine the nature and significance of progressive damages due to heavy loads on highway bridges. The study included a comparison of candidate bridges and control bridges of identical design but carrying different levels of truck traffic. Deck damage levels were considered, and predicted wheel load-induced patterns were identified for various levels of loading in the numerical study.
