摘要： 本文运用能量原理，推导出含有各层不同龄期的砼徐变、收缩内力计算公式．公式采用增量形式，以模拟实际施工过程的徐变收缩分析，并采用《规范》[5]提供的徐变系数，结合按龄期调整的有效弹性模量法，编制了相应的计算程序，将计算结果与实际模型试验作比较．
关键词: 徐变收缩, 劲性骨架砼, 时效分析
Abstract: In this paper,a formula of creep shrinkage internal force,which includes concrete layers of different ages by usingthe principle of Energy is derived.The movement farm is used in the formula in order to simulate the analysis of thecreep-shrinkage during actual construction processes.The creep cofficient provided by the Rule[5]and the effective elastic modulus method according to different ages are adopted in the formula to make out calculating procedures,comparingthe calculating results with those of the actual model test.
Key words: creep-shrinkage, stiffen framework concrete, time-dependent analysis
