Fatigue Loading and Design Methodology for High-Mast Lighting Towers. National Cooperative Highway Research Program (NCHRP) Report 718

摘要

This report provides criteria for the fatigue design of high-mast lighting towers (HMLTs). The report also includes a series of proposed revisions with associated commentary to the fatigue design provisions of the AASHTO Standard Specifications for Structural Supports for Highway Signs, Luminaires, and Traffic Signals. In addition, to ensure the fatigue design provisions are properly implemented into practice, design examples are also provided. The material in this report will be of immediate interest to highway design engineers.
