The paper presents an overview of different shear reinforcing methods forflat concrete slabs supported on columns. Typical reinforcing systems are described forboth new construction and for retrofitting existing slabs. These systems have beenstudied, tested and used in construction in the last several decades. The description ofthe reinforcement types, properties, methods of design, and construction issuesrelated to placement in slabs is included in this paper. The aim is to show theimportance of providing shear reinforcement in flat concrete slabs in the vicinity ofcolumns in terms of both strength and ductility. The theoretical background and themost important requirements for the effective shear reinforcement are emphasized anddiscussed. Selected experimental results are presented to illustrate the performanceof slabs with different types and placement configurations of shear reinforcements inslabs.
