Alternative Support Systems for Cantilever Signals/Sign Structures
During the 2004 hurricane season, several anchor embedment failures of the support structures of cantilever signal/sign structures occurred. A previous research program determined the cause of these failures was by concrete breakout due to shear on the anchors directed parallel to the edge of the foundation. The purpose of the current research program was to take the knowledge obtained on the previous research program and identify a suitable alternative support structure without the use of anchor bolts. After a literature review and experimental testing, it was determined that an embedded pipe with welded plates was a suitable alternative support structure. The torsion could be adequately transferred to the support structure concrete through the vertical torsional plates and the flexure could be adequately transferred to the concrete through the welded annular plate on the bottom of the pipe.
