Stress Redistribution of Composite Member Resulted from Creep[J]. Journal of Civil and Environmental Engineering, 2004, 26(1): 62-67. DOI: 10.11835/j.issn.1674-4764.2004.01.013.
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.
