Abstract This study examines the temperature field distribution characteristics and temperature effects during the prefabrication of composite box girders with corrugated steel webs (CBGCSWs), aiming to provide practical recommendations for controlling temperature-induced cracking and technical guidance for concrete mix proportions and placement processes. Based on field measurement data, a three-dimensional finite element model was developed to simulate the temperature effects at critical locations during the prefabrication phase. By varying the concrete mix proportions, initial casting temperature, and ambient temperature, the study elucidates the variation patterns of the temperature field during precast placement. The results show that… More >
