TRB’s National Cooperative Highway Research Program (NCHRP) Report 718: Fatigue Loading and Design Methodology for High-Mast Lighting Towers provides criteria for the fatigue design of high-mast lighting towers.

The report also includes a series of proposed revisions with associated commentary to the fatigue design provisions of the American Association of State Highway and Transportation Officials (AASHTO) Standard Specifications for Structural Supports for Highway Signs, Luminaires, and Traffic Signals.

Appendixes C through I of NCHRP Report 718 are available only in electronic format and are linked to below:

Appendix C—Stress Range Histogram Data and Regression

Appendix D—Wind Rosettes for Percent Occurrence and Mean Wind Speed

Appendix E—Site Specific Instrumentation Plans

Appendix F—Across Wind Excitation Algorithm

Appendix G— HMLT Modal Frequency Algorithm

Appendix H—HMLT Fatigue Life Evaluation

Appendix I—Aerodynamic Pressure and Hotwire Data
