coefficient of shrinkage meaning in English
干缩系数
收缩系数
Examples
- Coefficient of shrinkage
干缩系数 - The calculation modes of the coefficient of shrinkage and creep of the bulgy core concrete in steel tube are discussed . based on a few reasonable hypotheses and the stress - strain relation of concrete acquired by the " adjusting valid modulus depending on load time " method , a compact formula is reasoned out , which is applied to calculate the equivalent elastic modulus of the bulgy core concrete considering the affection of shrinkage and creep . so , the analysis of the affection on cfst arch bridge by shrinkage and creep can be progressed by pole - girder fem , further more , the analysis precision is quite high
本文还对核心膨胀混凝土特殊的收缩、徐变系数计算模式展开了探讨，在合理的假设前提下，采用“龄期调整的有效模量法”得到的混凝土的本构关系，推导出钢管内核心混凝土在考虑徐变影响后的等效弹性模量计算公式，并以此为基础采用杆系有限元方法来对钢管混凝土拱桥进行较高精度的收缩徐变分析。
