Optimizing the Geometric Configuration and Manufacturing Process of High Mast Illumination Poles

Galvanization is a widely used, effective method to protect steel from corrosion. However, in the past two decades, post-galvanizing inspections have reported the presence of cracks in high mast illumination poles (HMIPs), particularly at the toe of the welded connection between the pole and the base plate, on the pole. The main objective of this project is to provide guidance to engineers, galvanizers, and fabricators on how to minimize the likelihood of crack initiation during the fabrication process of high mast illumination poles (HMIPs). The research work includes the development of a finite element model that will account for the cumulative influence of welding and hot-dip galvanizing. This model will be used to conduct a parametric study in which the HMIP geometric configuration and parameters of the welding and galvanizing processes will be varied in order to determine their influence on the critical stress/strain demands that are induced during manufacturing. Different models will be evaluated corresponding to standard details used in Texas, Wyoming, and a historical socket connection that is present throughout the entire U.S. This information will be used to provide a better understanding of the root causes of galvanizing cracks in HMIPs, propose variations in the design and manufacturing practices of HMIPs with the aim of increasing their durability, and ensure safety for the traveling public.
