Fatigue Strength And Evaluation Of Sign Structures, Volume 2: Sign Structure Inspection Manual, Xuejun Li, Timothy M. Whalen, Mark D. Bowman

JTRP Technical Reports

This is the second volume of a two-volume final report presenting the findings of the research work that was undertaken to evaluate the fatigue behavior of sign structures and, based on that evaluation, to recommend an inspection plan that can be effectively used to detect and minimize possible deterioration due to wind induced loadings of sign structures. The study included a number of signs that are commonly used in Indiana: single-mastarm and double-mastarm cantilever sign structures, box-truss sign structures, tri-chord sign structures, and monotube sign structures. Sign structures with typical dimensions and details were selected as prototypes for each of …
