Abstract
This paper describes a methodology for prediction of fatigue response for highway support structures due to steady wind and wind gusts. Design issues concerning drag force application via AASHTO and ASCE provisions are detailed. A typical support structure is chosen as a case study example, in which stress ranges are found over a range of wind velocities. Results indicate the validity of the methodology and also illustrate that the ASCE wind load provisions are more conservative than those of the AASHTO criteria.
