AASHTO LRFDLTS-1

The first edition of the LRFD Specifications for Structural Supports for Highway Signs, Luminaires, and Traffic Signals incorporates and builds upon the design specifications found in the Sixth Edition of Standard Specifications for Structural Supports for Highway Signs, Luminaires, and Traffic Signals, which it supersedes. The specification includes current research on LRFD calibration, loads, and resistances plus relevant specifications from other AASHTO documents. Completely new sections on Fabrication, Construction, Inspection, and Asset Management based upon best practices have also been added.

The provisions of these load and resistance factor design specifications for structural supports for highway signs,luminaires, and traffic signals, hereinafter referred to as the Specifications, are applicable to the structural design ofsupports for highway signs, luminaires, and traffic signals (LRFD Structural Supports). The Specifications are intended to serve as a standard and guide for design, fabrication, construction, inspection, and asset management.

These Specifications are not intended to supplant proper training or the exercise of judgment by the Designer. Theyinclude only the minimum requirements necessary to provide for public safety. The Owner or the Designer may require the design, quality of materials, fabrication, construction, and asset management to be higher than the minimum requirements.

The design provisions of these Specifications employ the Load and Resistance Factor Design (LRFD) methodology. The factors have been developed from the theory of reliability based on current statistical knowledge ofloads and structural performance, including materials properties.

Seismic design is not included in these Specifications, and such procedures should be prescribed by the Owner.
