Standard Specification for Structural Supports for Highway Signs, Luminaires, and Traffic Signals
The totally revised specifications in AASHTO Standard Specifications for Structural Supports for Highway Signs, Luminaires, and Traffic Signals, 2001 contained significant improvements over past editions and was presented in a user-friendly specification / commentary side-by-side format. Despite this major update in the specifications, a number of technical issues still need further study. NCHRP Project 17-10(2) was initiated to address a number of prioritized technical topics. Addressing these topics would result in more comprehensive state-of-the-art supports specifications. Topics covered by Project 17-10(2) include assessing the wind loading provisions of the 2001 specifications, fatigue design for noncantilevered sign structures, foundation selection and anchor bolts, connection plate flatness criteria, bending about the diagonal for steel rectangular or square sections, drag coefficient transition for multi-sided sections, performance specifications for fiberglass-reinforced plastic poles, and a set of detailed design examples illustrating the application of the 2001 specifications. The project also outlines a strategic plan for future enhancements of the specifications and for conversion of the specifications to a load and resistance factor design philosophy and format.
