Abstract:
A comprehensive research program to investigate the suitability of a fiber reinforced plastic (FRP) for reinforced concrete is described. The investigation focuses on highway bridge decks and barrier walls. In determining the research needs, careful consideration has been given to the loads and environments to which highway bridges are subjected in northern North America. Short-term tension, creep, fatigue, and durability tests are being carried out on FRP specimens in the first phase of a three-phase program. Tests completed so far indicate a small yet noticeable change in strength and stiffness of FRP with change in temperature; small creep strain rates have been computed after 175 days of sustained loading, with satisfactory fatigue behavior under a tensile load cycling between 10 and 30 percent of the tensile strength.
