摘要:

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:

Based on the existing experimental data, the creep analysis of high-rise and long-span civil buildings can only be carried out by referring to the creep coefficient method in bridge structure or the creep method in hydraulic structure. Starting from the definition of creep coefficient, the median integral theorem and superposition principle are used to derive and modify the expression of the increment of creep shrinkage strain at different times of loading age and starting age, compare the difference in efficiency and accuracy between the finite element method applying creep coefficient analysis of creep and the initial strain method applying creep analysis of creep, and suggest that the initial strain method of creep degree should be used from the perspective of conceptual design to estimate the impact of creep on high-rise and long-span civil buildings.
