Abstract:In a continuing project on the shear strength of perforated reinforced concrete slabs, the compressive strength f,’ was initially determined from standard 6 x I2 in. ( 15 x 30 cm) cylinders, even though some of the test slabs were models with a geometrical scale factor of 2.5 of similar prototype slabs. The tests on the model slabs resulted in values of average shear stress at failure to square root of compressive strength which were approximately 7 to IO percent higher than prototype results when the 6 x 2-in. cylinders were used to obtain the model concrete strength. When model cylinders, 2.4 x 4.8 in. (6. I x 12.2 cm), for the scale factor of 2.5, were used for which the compressive strength was I5 to 20 percent higher than that found with 6 x I2-in. cylinders of the same concrete, the values. For the model and prototype were in much better agreement.
