During an earthquake, moments transferred at flat plate-column connections can produce significant shear stresses that increase their vulnerability to brittle punching shear failure. This guide provides recommendations for designing flat plate-column connections with sufficient ductility to withstand reversals of lateral drift without punching shear failure or loss of moment transfer capacity. Reinforced concrete flat plates with or without post-tensioning are discussed in this guide. Keywords: ductility; flat plate; post-tensioning; punching shear; seismic design; shear reinforcement; shear stud reinforcement.<\/p>\n
