This
paper presents a hybrid fiber reinforced polymer (FRP)-concrete deck system
using thin carbon FRP stiffened
plate for both deck replacement and new
construction applications. The plate has a nominal thickness of 6 mm and has
extruded stiffeners and shear ribs at the surface. The objective of this study
is to fully characterize the structural behavior of the deck system through
full-scale experiments and numerical
simulations. This paper discusses the
major results on interfacial characterization, short-term behavior of flexure
and shear, and long-term fatigue response. Satisfactory performance was
observed from the tests with a close correlation between the experimental
results and analytical simulations using
nonlinear finite element method and
typical constitutive material models for FRP composites and nonlinear concrete.
