Seismic Design of Punching Shear Reinforcement in Flat Plates - Guide
Also Known As:
ACI PRC-421.2-21 (IN-LB, SI) is a standard that focuses on the seismic design of punching shear reinforcement in flat plates. The standard recognizes that during an earthquake, there is a potential for significant shear stresses to be transferred at the connections between flat plates and columns. These shear stresses can lead to brittle punching shear failure, compromising the structural integrity of the building.
The purpose of this guide is to provide recommendations for designing flat plate-column connections that have sufficient ductility to withstand the lateral drift induced by earthquakes without experiencing punching shear failure or loss of moment transfer capacity. The standard covers both reinforced concrete flat plates and those with post-tensioning.
