"Concrete is daily becoming more important as a structural material. However, without steel reinforcement, concrete would never have attained such wide use since, being weak in tension, it must be combined with some other material to take the tension stresses and prevent the tension cracks in the concrete from opening an appreciable amount.
One type of steel reinforcement used particularly for footings, beams and columns is known as deformed bar. In this case deformations are placed on the bars at the time of rolling. These deformations act as mechanical anchorage in preventing the bar from slipping, thus allowing it to take the full tension stress and prevent cracks from opening.
In another type of reinforcement, smooth wires are drawn and welded into a mat which is particularly well suited to flat concrete slabs commonly used in building floors and walls, concrete highways, and airport runways. Its advantages are numerous, among them that the cost of installation is reduced since the mat is delivered with transverse wires already attached to the longitudinal wires by welding, and that the welds at the cross wires provide a positive anchorage which has been found in most cases to develop the breaking strength of the longitudinal wires in tension.
The primary concern of this study is with the detailed investigation of stress and crack control properties of welded wire reinforcement in order to provide data to aid in the improvement of its design"--Introduction, page 1.
