• Abstract:
  Portable roll-up signs are currently used by the Texas Department of Transportation for identification of short-term maintenance/work zones and emergency operations. These signs have fiberglass frames that directly support diamond-shaped and rectangular flexible sign faces. It has been frequently reported that these fiberglass frames have failed due to bending caused by natural winds or gusts generated by passing vehicles. This research project addressed three major issues: ; • Understanding the nature of wind loading on portable roll-up signs. ; • Identifying alternative materials for fiberglass frames. ; • Developing modified/new designs of portable roll-up signs.
