TESTS ON CONCRETE SLAB-COLUMN CONNECTIONS WITH STUD-SHEAR REINFORCEMENT SUBJECTED TO SHEAR-MOMENT TRANSFER.

Abstract

Test results of five full-scale reinforced concrete flat-plate connections with interior columns subjected to shear-moment transfer are reported. One specimen had no shear reinforcement, and the remaining four contained various arrangements of stud-shear reinforcement (vertical rods mechanically anchored at their top and bottom). The results confirmed the effectiveness of this type of shear reinforcement in increasing the shear strength and ductility of the connection. Code provisions suggested earlier for the design of shear studs are verified. Requirements for the dimensions of the anchor heads are suggested. The design of shear-stud reinforcement is demonstrated by a numerical example.
