Title: Some Implications of Recent Diagonal Tension Tests

Abstract:On the basis of the observed cracking which occurs when a beam fails in diagonal tension without stirrups and away from complicating loads and reactions, a hypothesis of unrestrainedz failure is developed. This hypothesis assumes each step in the cracking pattern as a tension failure which can be rationalized in terms of the conventional combined stress formula. Failures of beams somewhat restrained by reactions or loads, of beams of large shear span, and of footings are each discussed in terms of this hypothesis. Finally, two exploratory series of tests are reported. The first investigates the effect of extra or multiple loads and suggests that, higher shear strengths are available near supports. The second series indicates that much of the increased capacity associated with small shear spans is lost if the loads are applied as shears over the depth ’ of the beam or if the reaction is applied as a shear.
