Abstract:The years 2004 and 2005 were very active regarding hurricane activity in the Atlantic basin. Miami-Dade County experienced damages due to hurricanes Katrina and Wilma within a time span of barely two months. A significant proportion of street signs failed when these two hurricanes impacted Miami-Dade County and its surrounding communities. A traffic sign is considered as failed if it is leaning by more than 15 degrees from its vertical axis. Most of the street signs failed at their foundations, as shown in Figure A. This fact raised the need to find effective alternatives to secure traffic signs and reduce the number of damaged signs during moderate hurricanes. By improving the wind force withstanding capability of street signs, the costs associated with their repair and/or replacement are considerably reduced and the county’s valuable resources can be concentrated towards other aspects of the recovery process. Currently, the installation process for a standard street sign can be performed by one crew member in less than 30 minutes. The goal of this study is to evaluate a set of feasible alternatives for improving withstanding capabilities of the street signs without making the installation process more difficult.
