Abstract:
The ACI 318 Code procedure for shear design of prestressed concrete beams has remained substantially unchanged for more than 45 years. During their engineering practice and teaching prestressed concrete courses, the authors observed some anomalies in the ACI 318-14 shear design procedure for post-tensioned concrete beams. The article discusses their concerns and provides recommendations on addressing them.
