Abstract
In order to investigate the mechanical performance of the steel-concrete composite beam bridge under temperature, the stress and shear distribution of the three-span composite continuous beam bridge under temperature are investigated by combining finite element and theoretical methods. The results show that the maximum error ratios of the longitudinal stress obtained by the two calculation methods are 8.7% and 9.4% under the system temperature and temperature gradient, respectively. The maximum errors of the stress curves are less than 5%, which is in the acceptable range. The reasonableness of the finite element calculation results is proved and a basis for the mechanical performance analysis of the combined continuous girder under temperature is provided.
