Presents the results of a comprehensive series of tests on 8 in. (203 mm) thick extruded hollow-core (Dy-Core) slabs. Concentrated loads were applied at the edges of the slabs to produce localized shear or shear-torsion failures. No transverse deck reinforcement was provided. In most cases, the tests were carried through to failure. Based on the test results and a review of existing literature, it is recommended that allowable edge service loads can vary between 3.5 and 3.8 kips (15.6 to 16.9 kN) for the given geometry of the floor system, normal prestress forces and specified concrete strength.
