Three slab-column connections were tested to investigate the moment redistribution and punching shear resistance of flat plates under realistic loading and boundary conditions. The test specimens were essentially identical except that they had different reinforcement layouts within a span to impose different ratios of the end span and midspan design moments to total static moment. The test results showed that the different reinforcement layouts significantly and minutely influenced the moment redistribution and the punching shear resistance, respectively. The moment redistribution and punching shear resistance provisions in ACI 318 and EC2 were used to analyze the test results. New code recommendations for moment redistribution limit and punching shear strength are proposed based on the novel findings of this study.
