Cable-stayed bridges have been widely used in high-speed railway infrastructure. The accurate determination of cable's representative temperatures is vital during the intricate processes of design, construction, and maintenance of cable-stayed bridges. However, the representative temperatures of stayed cables are not specified in the existing design codes. To address this issue, this study investigates the distribution of the cable temperature and determinates its representative temperature. First, an experimental investigation, spanning over a period of one year, was carried out near the brid...
