收缩应变 shrinkage strain
contraction strain
- 通过对混凝土依时的自收缩应变和弹性模量测定,求得依时自收缩应力。
On the basis of measurement of time-dependent auto-shrinkage strains and elastic modulus of concretes, the time-dependent auto-shrinkage stresses may be calculated. - 结果表明,颗粒破碎程度与对其输入的塑性功密切相关;颗粒破碎的发生使钙质砂剪胀性减小,体积收缩应变增大,峰值强度降低。
The results indicate that particle breakage depends on the sample′s plastic work received during testing, and reduces the volume expansion and peak strength of the sands. - 阐述了砼结构体表比和约束比对温度和收缩应变和裂缝的影响程度,推导出R.C结构在四周无变位边界约束条件下的温度和收缩应变、应力及裂缝宽度计算公式和运用实例。
The formula of strain and crack width of temperature and contraction with no varying place constraint con detion are deduced, capale be design basis for crack control of R. C structure.
