Abstract
Due to the significant difference in thermal parameters between steel and concrete, complex temperature-related problems exist in steel–concrete composite bridge towers. Especially for the bridge tower with a particular type of Steel-Box-CFST section, the temperature distribution shows unique characteristics. To ensure the safety and regular use of the structure, it is necessary to analyse the temperature distribution mode of the composite bridge tower under solar radiation and to provide a method of temperature simulation at different conditions. In this paper, an indoor experiment in which the loading mode can be manually controlled has been carried out to study the temperature time-history and distribution in different loading conditions. The interface void between steel and concrete in CFST has also been detected. The results show that the outer steel box can protect the inner CFST from the temperature effect caused by solar radiation. A finite element model has also been established and verified by the experiment, providing a feasible way to simulate the temperature field under solar radiation.
