A wealth of information has been published on bond between concrete and bar reinforcement, but little is known about the bond properties of welded wire fabric reinforcement. Welded wire fabric is widely used as concrete rein-forcement, but bond properties have not been clearly established or specified in codes. The tests reported indicated that the bond stress theory as applied to smooth or deformed bars is not applicable to welded wire fabric. The latter’s resistance to slip is not a function of the contact area of the longitudinal wire in the concrete, on the contrary it is dependent on the anchoring ability of the transverse welded wires. The range of the sizes tested show that two welded transverse wires develop sufficient anchorage to develop the ultimate strength of the pulled-out wire.
