Theoretical Analysis of Creep and Shrinkage Effects in SRC Arch Bridge
In this paper, the concrete creep theory, compatibility equations, median theory and equilibrium conditions are used and the elastic aftereffect of concrete and creep shrinkage features of concrete restrained all around are considered to develop formulae of cross-section stress redistribution resulted from concrete creep and shrinkage. The formulae which are simple and convenient to use are applied to Wanxian Changjiang Bridge (420m in span) for the model test analysis of creep and shrinkage. The obtained results are compared with those of model test and the agreement between them is very good. The main factors to affect the stress of this type of bridge are indicated.
