Abstract
The use of post-tensioning to increase the strength of steel beams in beam and concrete-slab bridges is shown to be feasible. The purpose of the study is to determine a technique for increasing the capacity of the bridges to meet today's loadings. The results of testing a half-scale model of an existing bridge indicate that post-tensioning can be used with only minor deck cracking. Comparisons of the data from the model with results using orthotropic plate theory indicate that this theory can be used as a preliminary design methodology for determining the required prestress force and its location for strengthening existing bridges.
