Some tests on reinforced concrete beam-slab panels

Abstract

Synopsis Results of tests on ten reinforced concrete beam-slab panels are reported. The panels, which were subjected to a uniformly distributed load, were square and consisted of two-way-spanning slabs supported on, and integral with, edge beams. Variables in the investigation included the relative strengths of the beams and slabs, the layout of the slab reinforcement, and the detailing of the corner connexions. The behaviour of the slabs is discussed and, in particular, the ultimate loads are compared with those predicted by simple yield-line theory. The limitations of this theory are discussed and suggestions are made for a more accurate method of calculation to be used in design which would effect some economy in reinforcement.
