WebTesting of many reinforced concrete beams has shown that the average stress within the compressive zone is 0.85β 1 fc ', and the resultant location is β 1 c /2 from the face of the concrete beam, as shown in Figure … Webincreasing the allowable concrete horizontal shear capacity, structural testing of composite prestressed beams without horizontal shear ties was conducted. The horizontal shear capacity was established for uniform and point load conditions, four levels of interface roughness, and three ratios of slab to beam concrete compressive strength.
