To investigate the effects of diameter and inclination on the vertical temperature gradient (VTG) of concrete-filled steel tubular (CFST) arches, this study conducted temperature field tests on three CFST segment specimens with diameters of 426 mm, 750 mm, and 1000 mm, as well as an arch specimen wi...
