Headed Studs in Concrete: State of the Art

Headed studs are smooth or deformed bars, usually short compared to the lengths of concrete members, with forged or welded heads for anchorage at one or both ends; they are used instead of conventional reinforcing bars anchored by hooks and bends. This article discusses several practical applications where the use of headed studs is appropriate. The authors note that the main advantages are simpler installation, less congestion of reinforcement, improved confinement, and more effective anchorage. The authors discuss applications for headed studs in slabs and footings, beams with thin webs, crossties in columns and walls, precast beams, deep beams and pile caps, and in beam-column joints. They conclude that use of a headed bar, as opposed to a bar with a hook, is advantageous in applications where there is demand for the yield strength at a section of the bar close to its end.
