EVALUATION OF BOLTED-BASE STEEL CHANNEL SIGNPOST

A recent survey has shown that the steel flanged channel post, or U-post, is the most widely used type of sign support in the United States. In the past, it has been common practice to drive the full-length U-post into the ground. To facilitate its installation, a simple stud-signpost support sytem has been developed. Initially, a relatively short stub post is driven into the ground. Then the signpost, with sign panel attached is bolted to the stub. A retainer-spacer strap in the bolted connection serves to provide a snug fit between the signpost-to-stub connection and to help control the impact trajectory of the design panel and the signpost. Static load tests and full-scale vehicle crash tests were conducted to evaluate the stud-signpost system. Crash tests of both single and multiple-post sign configurations were conducted in accordance with current standards and guidelines. The stud-signpost system satisfied current safety criteria in all cases. This paper describes these tests and their results. /Author/
