Leveraging 80 ksi WWR as a Structural Reinforcement Substitution
Date: April 2022
Welded wire reinforcement (WWR) is commonly manufactured to achieve a yield strength of 80 ksi, in turn presenting itself as a savings-laden structural alternative to the 60 ksi mild steel reinforcement that continues to dominate the reinforced concrete construction landscape.
For appropriate applications, simple equivalency calculations can be carried out by WWR manufacturers’ technical staffs to determine a lesser cross-sectional area of WWR that provides “equal strength” to that of an originally-specified 60 ksi reinforcement solution. The general equivalency equation is presented below.
