摘要

Twenty-nine specimens were tested to investigate the fatigue resistance of high-performance steel (HPS-485W) (70 W) continuous plate with punched holes. Specimen thickness, hole diameter, and method used for creating the holes were varied to examine their effect upon fatigue resistance of punched connections utilizing high performance steel. Eight of the 29 specimens were drilled or subpunched and reamed specimens, all of which rated as Category B details. The remaining 21 specimens had punched holes and rated considerably below a Category B. Results from this investigation suggest that current restrictions mandated by some state DOTs concerning punching holes are not overly restrictive when HPS-485W (70 W) is utilized. Performance of drilled and subpunched and reamed specimens met (or exceeded) 2004 AASHTO requirements for Category B details.
