Field and Laboratory Performance of FRP Bridge Panels

The objective of this research project is to examine the use of FRP materials for bridge construction. In particular, this project utilizes glass FRP (GFRP) honeycomb sandwich panels. The installation of three bridges, one comprised solely of the FRP panels and two comprised of the FRP panels supported by steel girders, is outlined. Furthermore, results of preliminary testing conducted on the FRP panels are summarized. An in-situ bridge load test was conducted; a comparison is made between the theoretical and experimental values of maximum deflection and a discussion of the load transfer between panels is presented. Additional testing was conducted on an identical bridge panel section in the laboratory; results in terms of a load-deflection diagram, ultimate load, and the failure mechanism of the beam are noted herein.
