MENOMONEE FALLS, Wis. (April 18, 2022) – Three years ago when Marc Maguire, assistant professor of construction programs at the University of Nebraska-Lincoln, started investigating a new stranded wire product for bridge girder reinforcing he thought the best strands for bridge construction were the industry standard 7-wire strands.

After running a multitude of analyses, Maguire and student researchers found that 19-wire 1-1/8 in. diameter strands outperform the typical 7-wire 1-1/6 in. diameter strands and allow bridges to reach unprecedented lengths. Further tests conducted by the Durham School of Architectural Engineering and Construction with the help of Enerpac hydraulic tools examined the bond strength, force transfer, and development length of the 19-wire strands.

"Traditionally, 19-wire strands are not often used in the U.S. because they are not widely available and they are much larger than standard strands," said Maguire. "We wanted to show that there was an alternative option to the common 7-wire strand--one that can perform at the same level, if not better."
