Abstract:
For the rate-type creep law of concrete (Eq. 1), the general problem of creep analysis is converted to a sequence of elasticity problems with intial strains. It is shown how this general method can be applied to the analysis of composite beams. The method is demostrated by a numerical example. It is found that statical indeterminancy of supports significantly alters the effects of shrinkage in composite beams.
