|Mechanical Splice Testing Standard Developed by Steel Reinforcement Subcommittee
Mechanical splices for steel reinforcing bars are crucial devices used in the reinforced concrete construction of bridges and buildings.
Despite the fact that there are many manufacturers and suppliers of mechanical splices, there has not been a consensus standard for testing such devices. ASTM Committee A01 on Steel, Stainless Steel and Related Alloys has met this need with a recently-approved new standard, A 1034, Test Methods for Testing Mechanical Splices for Steel Reinforcing Bars.
We began work on this activity a few years ago, recognizing that an important niche can be filled by this standard, says David P. Gustafson, Concrete Reinforcing Steel Institute, and chair of Subcommittee A01.05, Steel Reinforcement, which has jurisdiction over A 1034. Subcommittee A01.05 Secretary Heinz Nierlich, Dywidag Systems International USA Inc., adds, Obviously, its important that mechanical splices perform under the rigorous loading conditions a structure would be subjected to, for example, earthquakes. The test methods contained in A 1034 are applicable to any type of mechanical splice manufactured to join steel reinforcing bars of any strength level (grade of steel).
