Designing Tendon and Reinforcement Configurations for Punching and Postpunching Performance Demands of Posttensioned Concrete Flat Plate Slab–Column Joints

The punching shear and postpunching strengths of slab–column joints (SCJs) are the critical indicators of the resistance of posttensioned concrete flat plate structures to progressive collapse. These two capacities, however, are governed by distinct failure mechanisms and typically require different design strategies...
