Title: Stud Shear Reinforcement for Flat Concrete Plates
Author(s): Abdel-Salam Mokhtar, Amin Ghali, and Walter Dilger
Publication: Journal Proceedings
Appears on pages(s): 676-683
Keywords: columns (supports); connections; cracking (fracturing); deformation; ductility; economics; flat concrete plates; flexural strength; punching shear; reinforced concrete; shear connectors; shear strength; structural design.
Abstract:Results of tests to failure on eight full-sized slab-column connections subjected to concentric loads are presented. One specimen had no reinforcement, while the remaining seven specimens were reinforced against punching shear by "shear studs," vertical bars welded at their tops to square anchor heads and at bottom to a steel strip. Test results verified the effectiveness of the stud reinforcement in lightweight slabs, determined how strength is affected by provision of concrete cover above and below the anchors, and served as a further verification of design procedure for this type of reinforcement. A numerical example demonstrates design of shear-stud reinforcement at an interior column of a flat plate.
