- Abstract
The use of normal-strength (Grade 60) and high-strength (Grade 80) headed bars as transverse reinforcement can improve the constructability of reinforced concrete structures. However, the ACI 318-19 Code does not allow the use of headed bars as transverse reinforcement in deep beams. ACI 318-19 also does not allow engineers to take advantage of the increased yield strength of Grade 80 reinforcement for use as shear reinforcement. This paper presents an analytical evaluation of shear-critical deep beams that use high-strength headed reinforcement. Six recently conducted largescale experiments are modeled using the two-parameter kinematic theory, the nonlinear finite element tool VecTor2, and strut-and-tie methods described in codes. The predictions are compared with experimental results. A parametric study is conducted to evaluate the influence of the quantity of transverse reinforcement and yield stress of the transverse reinforcement on the response of shearcritical deep beams.
