Abstract:
The experimental work and studies reported in this article were undertaken to study the effects of dimensional changes on the unit shear strength of reinforced concrete beams. The tests included the following variables: beam depth; maximum aggregate size; and bar cover, size, and spacing. Studies of the experimental results suggested that if changes in the considered variables are controlled so that the variables change in the same proportion, the variation in the experimental results is not more than the expected scatter in results from nominally identical beams.
