Results from a series of static tests on one-way reinforced concrete slabs are summarized. The slabs were loaded with a uniform pressure and tested to large deflections. Parameters varied included the amount, spacing and type of shear stirrups; the configuration of principal reinforcement; and rotational restraint of the slab supports. Results indicate that at spacings greater than about one-half the slab thickness, stirrups have little effect on resistance. Optimum configuration for principal reinforcement is to place it so that about 75 percent is in the tensile zone and 25 percent is in the compressive zone. Additional study results are discussed.
