- Abstract
Different creep coefficients of concrete layers in composite beam will cause redistribution of stress and additional stress in section. Based on the concept of strain compatibility approach, in this paper,the authors deduced a differential equation of the additional inner forces resulted from creep. Thereafter, the authors proposed an equation to calculate stress redistribution of steel and concrete composite beam, concrete composite beam and concrete strengthening member. At last, the formulas of additional stress of the section were proposed.
