初应变 meaning in English
initial strain
Examples
- This method is not only convenient to consider tubular initial stress and temperature initial strain , but also is of self - superiority , computing result for calculated examples indicate that this method is feasible
该方法便于考虑钢管初始应力和温度初应变，而且有其自身的优越性，算例计算结果表明，该方法是可行的。 - According to the theory of equivalent time , creep as a function of equivalent time is expressed . by fitting experimental data , parameters of creep in equivalent time field are obtained ; initial strain implicit solution of elastic creep equation in equivalent time field is derived
根据等效时间理论，将徐变表示为等效时间的函数，通过拟合试验数据，得出等效时间域弹性模量和徐变度公式的计算参数，推导了等效时间域的弹性徐变方程的初应变隐式解法。 - 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 - 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
