  1. The calculation modes of the coefficient of shrinkage and creep of the bulgy core concrete in steel tube are discussed. based on a few reasonable hypotheses and the stress - strain relation of concrete acquired by the " adjusting valid modulus depending on load time " method, a compact formula is reasoned out, which is applied to calculate the equivalent elastic modulus of the bulgy core concrete considering the affection of shrinkage and creep. so, the analysis of the affection on cfst arch bridge by shrinkage and creep can be progressed by pole - girder fem, further more, the analysis precision is quite high
