Field instrumentation and monitoring of KDOT fiber composite bridge for long-term behavior assessment

This report discusses results from an analytical study concerning the long-term evaluation of two fiber-reinforced polymer composite bridges in Kansas. Background on current non-destructive evaluation methodologies for monitoring structural systems and typical sensors that are used with non-destructive evaluation techniques are discussed. The results of the finite element models of the bridges are presented. A procedure for selecting and installing appropriate systems for non-destructive evaluation of the fiber-reinforced polymer composite bridges is described.; The purpose of this thesis is to address specific questions proposed by the Kansas Department of Transportation regarding the performance of fiber-reinforced polymer composite decks installed in the fall of 2000 on two existing bridges, and to identify possible long-term performance problems. The main objectives are: (1) To determine if composite action develops between the fiber-reinforced polymer composite deck, saddle and steel girder. And if composite action does develop, estimate the improved capacity of the bridge. (2) To determine if vibration of the bridge may lead to structural deterioration. (3) To evaluate the effectiveness of the bolted connections. (Abstract shortened by UMI.)...
