| 摘要： | This paper discusses results from an analytical study concerning the long-term evaluation of two fiber-reinforced polymer composite bridges in Kansas. A background on current non-destructive evaluation methodologies for monitoring structural systems and typical sensors that are used with non-destructive evaluation techniques is 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 paper 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 1999 on two existing bridges, and to identify possible long-term performance problems. The main objectives are: 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; to determine if vibration of the bridge may lead to structural deterioration; to evaluate the effectiveness of the bolted connections. |
