Abstract:
The article describes the rationale for changes in ACI 318-19 that will address concerns and inconsistencies related to shear strength of deep beams and D-regions while maintaining the essential characteristics of design according to the strut-and-tie method. The changes in the Code relate to the strength of struts and requirements for minimum distributed reinforcement. Analyses of data from previous studies and a recent test program were used to evaluate the influence of diagonal tension on the strength of struts.
