Testing of Overhead Box Truss Chords and Flanges

Overhead box truss structures are used every day by motorists to navigate through the interstate system. It is typical for an overhead box truss to experience multiple types of loading over its life span. One of the most common loading types an overhead sign structure will experience is wind loading. This study provides a synthesis of results from destructive testing of damaged overhead box trusses. Testing was done to provide a theoretical and experimental analysis in order to understand how damaged trusses would react under the most severe wind loads in Ohio.
