Composite Bridges: Health Monitoring with the Diagnostic Prognostic System (DPS) and an Evaluation of a Temporary Field Repair System
Abstract
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 field repair techniques for composite bridges. In previous papers, information regarding calibration of material properties and fatigue testing with composite treadways was presented. Areas explored to date have been health monitoring with the Diagnostic Prognostic System (DPS) and a structural evaluation of a temporary field repair system. Health monitoring of a composite beam with DPS entailed comparing live strain data to archived strained data in three different 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.
