Abstract:
An investigation of the behavior of concrete slabs reinforced with pultruded FRP (fiber-reinforced plastic) gratings is described. Data from tests on small-scale and full-scale slab specimens obtained from three different experimental programs, beginning in September of 1989, are reviewed. Particular attention is paid to the description of failure modes, crack patterns, flexural stiffness, and shear response of the slabs. Analytical methods, based on those developed for steel reinforced concrete slabs, used to obtain predictions of the ultimate strengths and the flexural stiffnesses of the slabs, are described. Comparisons between experimental data and theoretical predictions are presented.
