Deflection Criteria for Wind Induced Vibrations in Cantilever Highway Sign Structures

摘要

This study considers the vibratory characteristics of cantilever highway sign structures. During the course of the study four structures were instrumented to experimentally determine their vibration characteristics. Analytical studies were also performed, using finite element techniques. The analysis considers several types of wind loading on the structure. The analysis shows that high stress levels can be expected in these structures under severe wind conditions.
