Wind Loading as a Fatigue Factor on Lighting Standard Mounting Bolts

摘要

The objective of the project was to characterize the relationship between stress range, frequency of application, and cumulative cyclic loading of properly installed lighting standard anchor bolts under a variety of wind speeds and directions. Measurements were made for wind conditions versus lighting standard anchor bolt tension loading. The high-strength anchor bolt assembly for a Caltrans Type 31 lighting standard is a conservative design. Wind loads experienced during the project did not produce a significant stress in the anchor bolts of a Type 31 lighting standard with a nonslip base design and a 20- or 30-foot arm.
