Response of No-Name Creek FRP Bridge to Local Weather, Technical Summary.

摘要

A long-term remote monitoring system was designed to investigate the response of the No-Name Creek composite bridge to the local weather. The characteristics of the bridge temperatures, the temperature differences of the two panel surfaces and the relationship between the temperature difference and the deflection were investigated with respect to the different weather patterns. Twelve thermal sensors were embedded into the FRP bridge panels. In addition, 3 laser sensors were installed to measure bridge thermal deflection. Between October 2004 and September 2005, bridge temperature and deflection were measured at 20 minute intervals. Relations between weather condition, temperature distribution and bridge thermal deflection for that bridge were analyzed.
