Title: Tensile Anchorage Behavior of Deformed Reinforcement in Grouted Concrete Masonry
Author(s): Tariq S. Cheema and Richard E. Klingner

Abstract:Failure modes, tensile capacity, and bond-slip characteristics of monotonically loaded Grade 60 deformed reinforcement anchored in grouted concrete masonry were investigated experimentally. Seventy-three tests were conducted on No. 4, 8, and II bars placed in single-wythe concrete masonry walls filled with pea-gravel grout. The test setup was designed for minimum interference with the stress state around the bar. In addition to pullout and splitting failures, which are also characteristic of bars anchored in concrete, a unique failure mode involving uplift of masonry along bed and head joints was observed. Bond-slip results differed significantly from those of some models now used for reinforced concrete.
