Title: Design for Punching Shear in Concrete
Author(s): S. Megally and A. Ghali
Publication: Special Publication
Appears on pages(s): 37-66
Keywords: columns (supports); connections; ductility; footings; prestressed concrete; punching shear; reinforced concrete; seismic design; shear strength; slabs; structural design
Abstract:Design of connections of columns to flat slabs to ensure safety against punching failure is presented. The connections transfer shearing forces and moments between the columns and slabs. The objective is to cover the design procedure in most practical situations including: interior, edge and corner columns, prestressed and nonprestressed slabs, slabs with openings and slabs with shear reinforcement. The ACI 318-95 code requirements are adhered to where applicable. The designs are demonstrated numerical examples. Design of shear reinforcement in raft slabs, footings and walls subjected to concentrated horizontal forces is also discussed.
