摘要

Composite bridges offer many advantages compared to current steel and aluminum bridges including their lightweight and superior corrosion resistance properties. This paper presents the results of a comprehensive on-going research program to develop innovative Diagnostic Prognostic System (DPS) and a structural evaluation of Composite Army Bridge (CAB) system. The DPS is founded on three technologies, namely; optical fiber sensing, remote data transmission,, and virtual testing. In developing this system, both laboratory and virtual test were used in evaluating different potential damage scenarios. Health monitoring of a composite beam with DPS entailed comparing live strain data to archived strained data in various bridge locations. For temporary field repairs, a family of composite chords was subjected simple ramp loads in search of ultimate strength. As such, composite bridge specimens showcased their strengths, heralded the viability of virtual testing, highlighted the efficacy of field repair, and confirmed the merits of health monitoring.
