ultimate tensile strain

基本解释

The correlation between the compressive strength and axial tensile strength of RCC with placing joint and ultimate tensile strain of placing joint of RCC layers have been obtained.
通过试验研究给出有层面碾压混凝土抗压强度、面轴拉强度与层面极限拉伸值间相关关系。
Considering the randomness of strength and deformation of concrete material, a mathematic approach of producing random variables series of concrete ultimate tensile strain is proposed.

When the ratio not more than 0.2, CFRP tensile strain can reach or exceed the permissible strain at ultimate capacity state, and therefore CFRP can work efficiently.
当配筋特征值不大于0.2时，承载能力极限状态下碳纤维片材的拉应变可以接近或超过允许拉应变，因此可以有效地对受弯构件正截面承载力进行加固；

极限拉应变
The ultimate tensile strain is meaning the biggest strain at the time that concrete destroy. It's a important factor of concrete's cracking.
混凝土极限拉应变是指混凝土受拉断裂前所能承受的最大拉应变,它是影响混凝土开裂的重要因素之一。
