Abstract
This report documents the design, testing and implementation of a bridge strengthened by installing carbon fiber reinforced polymer (CFRP) plates to the bottom flange of girders in the positive moment region. The bridge is a three span continuous span steel structure located in Pottawattamie County with supplemental steel cover plates in the negative moment regions. Based on calculations completed by the bridge owner, it was determined that the positive moment regions of the interior girders in both the end and center spans of the selected bridge were overstressed. Design computations indicated that the overstressed girders could be adequately strengthened by the addition of CFRP plates bonded to the bottom flange of the girders.
