Punching of Restrained Reinforced Concrete Slabs
Punching tests on twelve restrained reinforced concrete slabs are reported. The slab panels were supported and restrained on all four sides by edge beams. The influences of the degree of edge restraint, percentage of reinforcement steel and span-depth ratio of the slabs on the structural behavior and punching shear capacity of the slabs were investigated. The tests were carried out to provide basic information on the real punching behavior of restrained reinforced concrete slabs subjected to concentrated loading, and the enhanced punching shear strength due to the development of compressive membrane action caused by restraining action atthe slab boundaries. Comparisons between the experimental strengths and the ultimate loads predicted by Johansen's yield-line theory and the codes of practice (BS 8110 and ACI 318) are also presented.
