Structural Engineering Research On-Call Services Task 2 - Aluminum Truss Overhead Sign Support Flange Damage Assessment

A variety of structural supports exist to mount signs along highways. One type of support is a truss that spans the width of the highway that allows for the placement of overhead signs. These trusses are subject primarily to wind and gravity loads. The connections between the chords and the diagonals are typical fillet welded. Fillet welds are a fatigue prone detail and the welding potentially can leave a heat affected zone which affects the strength of the joints and the members. A truss with severe cracking near Obetz, Ohio was identified by the Ohio Department of Transportation and removed from service. Research team members inspected the trusses in the field on March 14, 2018 after they were removed from service. The cracking was mapped and elements of the truss including cracked and undamaged joints were removed from the truss and transported to the University of Toledo.
