Abstract: A review of the different types of shear reinforcement for concrete flate plates is presented and the difficulties encountered when these are used in practice are reviewed. Practical shear reinforcement should efficienty increase the shear strength and ductility of the slab-column connection, and should be easy to fabricate and install. New Type of shear reinforcement which satisfies these requirements is presented. An individual reinforcing element is in the form of vertical bars with mechanical anchorages at the two ends. The size and shape of the anchors are examined as well as the arrangement of the shear elements around the column. From the results of 40 full-size tests, rules for the design of the new type of shear reinforcement are given in the form of suggested revisions to the current codes.
