Section Stress Redistribution of Concrete Composite Member Caused by Creep
Composite member refers to the cross section formed by two different concrete combinations or the combined cross section formed by concrete and steel combinations. In this paper, a numerical model for the analysis of stress redistribution caused by creep is established on the basis of the deformation coordination relation of composite section, which is the cause of additional stress induced by creep. The validity of the numerical simulation method is verified by quoting the additional theoretical value of internal force caused by creep of section stress redistribution based on the concrete aging creep theory in the existing literature, and the variation rule of additional internal force of section stress redistribution under different strength and age is given according to the numerical simulation method.
