Title: 421.2R-07: Seismic Design of Punching Shear Reinforcement in Flat Plates

Abstract:Note: A newer version of this document exists. This document was replaced by 421.2R-10.
During an earthquake, the unbalanced moments transferred at flat plate-column connections can produce significant shear stresses that increase the vulnerability of these connections to brittle punching shear failure. This report gives recommendations for designing flat plate-column connections with sufficient ductility to go through lateral drift without punching shear failure or loss of moment transfer capacity.
