Abstract

An experimental study was conducted in which 37 reinforced concrete deep beam specimens were tested. The specimens are some of the largest deep beams ever tested in the history of shear research. The data from the experimental program and from a database of 179 deep beam tests in the literature were used to assess the accuracy and conservatism of the strut and tie modeling provisions of ACI 318. In addition, the effects of the following variables were evaluated: distribution of stirrup legs across the web, triaxial confinement via concrete surrounding CCC and CCT nodal faces, quantity of web reinforcement, member depth, and a/d ratio. Based on the experimental findings of the study, suggested improvements to the ACI 318 STM provisions are discussed in this paper.
