The creep of concrete considering the delayed effect of elasticity is a deve-lopment of the applied creep theory. The procedure of estimating the stress re-distribution due to creeping of concrete of a segmentally cast continuous stru-cture loaded at different age of concrete, can be simplified by use of the mo-dified modulus of elasticity E.=E/1+ρφ, but the determination of the coeffi-cient ρ in [2] involves a lot of diagrams based on different ages of loadingτ_?.,theoretical thickness of members h_(?), the final yielding flow φ_(fk) and de-layed effect of elasticity φ_d,that leads to a complicated computer work. Thecoefficient ρ proposed by the author here taking account of delayed effect ofelasticity gives a result well consistent with that calculated by the former co-efficient. Derivation of formulas for calculating stress redistribution by finite ele-ment method is given in this paper, and some examples by hand calculation arealso given as an illustration.

计入弹性延迟影响的混凝土徐变是徐变实用理论的发展。采用混凝土徐变换算弹性模量E_φ=E/(1+ρφ),计算由不同加载龄期构件组成的超静定结构徐变内力重分布,可使计算简化。文献[2]根据不同加载龄期τ_o、构件的理论厚度h_(th)、最终流变值中φ_(f,k)及延迟弹性影响φ_d作出了大量图表,实现电算有较多困难作者按老化理论的狄辛盖尔公式推导,得到换算弹性模量公式中的龄期系数ρ=1/(1-e~(-φ)-1/φ,以此得到的内力量分布结果与用精确龄期系数计算的结果甚为接近。文中还采用有限元法推导了超静定结构徐变内力重分市的计算,并手算了几种类型的例题。
