摘要
在超静定砼及钢筋砼结构中,由于砼的干缩将于结构中产生内力和应力,设计中通常将此项内力化作相应的温降来分析,砼干缩并产生应力的同时,相应的徐变也将发生。本文分析了两者之间的相互影响,给出了简单适用的折减系数,可供设计参考。
In the concrete and reinforced concrete indeterminate structure, shall produce the inner force and stress due to shrinkage of concrete. Under normal condition, this inner force can be analysed as the reduce of temperature. As the shrinkage is production, the creep of concreteproduce at the same time. This paper has calculated the relation between this two factor, and had siven a reduce coefficient. Can berefered by designer.
