shrinkage strain meaning in English
收缩应变；收缩变形
Examples
- Shrinkage strains are mdependent of the stress conditions in the concrete
混凝土的收缩是一种自发的变形，并不依靠作用在混凝土上的外力。 - Creep analysis methods of high - rise buildings and large span buildings can only refer to creep coefficient method in bridge engineering or the method of degree of creep in hydraulic construction engineering under the present experiment conditions . in this paper , the incremental expressions of concrete creep and shrinkage strain when the initial computational age is not the same as the loading age are derived and corrected from the concept of concrete creep coefficient and the mean value theorem of integral and the principle of superposition . the differences of efficiency and accuracy of creep analysis between the finite element method with creep coefficient and the initial stress method with degree of creep are presented . this paper suggests that engineers should use the initial stress method with degree of creep to estimate the influences of creep on high - rise buildings and large span buildings on the basis of conceptual design
基于现有的试验资料，高层及大跨度民用建筑的徐变分析只能参照桥梁结构中的徐变系数方法或水工结构中的徐变度方法进行.从徐变系数的定义出发，利用积分中值定理和叠加原理，推导并修正了加载龄期与起算龄期不同时徐变收缩应变增量的表达式，对比了应用徐变系数分析徐变的有限元法和应用徐变度分析徐变的初应变法在效率和精度上的差别，并建议应从概念设计的角度出发，采用徐变度的初应变法来估算徐变对高层及大跨度民用建筑的影响 - Through the experiment of the interfacial bonding shear strength and the shrinkage strain of concrete , the influence of the interfacial roughness of used concrete surface and interfacial bonding agent to interfacial bonding strength is revealed ; new concrete component and the shape and size of concrete slab are main factor affecting the shearing stress in layers
试验结果表明：老混凝土粘结面的粗糙度和界面粘结剂类型对新老混凝土界面粘结强度影响很大；新铺混凝土材料和混凝土路面板形状尺寸是影响新老混凝土粘结面收缩剪应力的主要因素。 - Abstract : creep analysis methods of high - rise buildings and large span buildings can only refer to creep coefficient method in bridge engineering or the method of degree of creep in hydraulic construction engineering under the present experiment conditions . in this paper , the incremental expressions of concrete creep and shrinkage strain when the initial computational age is not the same as the loading age are derived and corrected from the concept of concrete creep coefficient and the mean value theorem of integral and the principle of superposition . the differences of efficiency and accuracy of creep analysis between the finite element method with creep coefficient and the initial stress method with degree of creep are presented . this paper suggests that engineers should use the initial stress method with degree of creep to estimate the influences of creep on high - rise buildings and large span buildings on the basis of conceptual design
