FRC DECK SLABS WITHOUT TENSILE REINFORCEMENT

Abstract

Nearly all the research and development work on the steel-free FRC deck slabs has been reported. It has been shown that the internal arching action of the deck slabs of girder bridges can be harnessed by connecting the slab to the girders by shear connectors and through transverse confinement provided by external bars or straps. The extensive static and dynamic tests on both small- and full-scale laboratory models have not only given confidence in the very high strength of the proposed deck slab but have also resolved the issue of various construction details.
