混凝土的收缩和徐变 meaning in English
creep and shrinkage of conerete
Examples
- Hence , in order to guarantee the engineering quality , we must reduce the concrete shrink and creep furthest in constructing and design
因此在预应力混凝土结构的设计和施工中，应尽量减少混凝土的收缩和徐变，保证工程质量。 - Further more , the prestress loss , which is caused by the shortened beam member due to concrete shrink and creep , is of disbenefit to prestress concrete structure
不仅如此，混凝土的收缩和徐变使构件缩短而引起预应力损失，对预应力混凝土结构十分不利。 - This thesis has made the contrast test of shrink and creep for plain concrete and concrete filled steel tubes on the basis of long term in - door test , obtains the principles of shrink - creep of concrete filled steel tube , simulates the test data , analyses and contrasts the coefficient of shrink and creep , thus offers reference for the calculation mode of creep , furthermore by introducing reasonable assuming at the same time , develops the calculation formula of equivalent elastic modulus at the same time , develops the calculation formula of equivalent elastic modulus , adopts common structure analyses procedure ansys to calculate the redistribution of section stress in the steel tube and concrete during operation
本文在长期的室内试验的基础上对素混凝土和钢管混凝土做了收缩和徐变的对比试验,得出钢管混凝土的收缩徐变规律,对试验数据进行了拟合,对钢管混凝土的收缩和徐变系数进行了分析和比较,从而为钢管混凝土的徐变计算模式提供参考,同时通过引入合理的假定,并结合由“龄期调整有效模量法”导出的混凝土徐变本构关系,推导出了钢管核心混凝土考虑徐变影响后的等效弹性模量计算公式,并以此为基础采用通用结构分析程序ansys对成桥后钢管和混凝土应力重分布进行了计算。
