Fatigue of Deformed Welded-Wire Reinforcement

Use of welded-wire reinforcement (WWR), as an alternative to traditional mild steel reinforcing bars, has many advantages such as higher yield strength and being produced under higher quality control standards. Its use also results in lower labor costs associated with construction. However, many designers are reluctant to use WWR as an alternative to mild steel reinforcing bars due to unavailability of fatigue design guidance in the American Association of State Highway and Transportation Officials' AASHTO LRFD Bridge Design Specifications. This paper reports on a fatigue testing program of deformed, high-strength WWR. Based on results of this testing program, a conservative stress range formula for WWR is presented. This formula has been adopted for use in the 2007 Interim AASHTO LRFD Bridge Design Specifications. Full monotonic axial tensile stress-strain relationships are also presented.
