- Abstract:
- The bridge panel of sandwich structure was manufactured by using pseudotsuga taxifolia glulam as core materials and glass fiber reinforced polymer (GFRP) as surface course. The bending experiment of GFRP-pseudotsuga taxifolia glulam beam was carried out based on basic mechanical property of pseudotsuga taxifolia glulam core materials and GFRP. From the bending experiment, the loadmidspan deflection curve and GFRP loadmidspan strain curve were got, and the test value was compared with theoretical value of bending stiffness. It brought up a whole structured design process of a sandwich structure bridge deck, and gave the design parameter of bridge deck. The study results show that using GFRPpseudotsuga taxifolia glulam bridge deck into girdercomposite bridge panel is feasible.
