Abstract
Since Kyung-Bu High Speed Line has been introduced, a railway electrification has been proceeded rapidly. Therefore, in this study, a specification and application standard for an overhead catenary supporting thin walled steel pole using STKT590 material are proposed in order to improve an economical efficiency. To decide the specification, strength analysis, deflection analysis, deflection test and fracture test are performed. If the supporting structures using high strength materials such as STKT590 are installed, the advantages of cost by the materials price reduction and demand and supply are expected.
