摘要
根据混凝土收缩徐变机理,对混凝土收缩徐变效应的主要影响因素进行了分析,分析结果表明:徐变系数和收缩应变随构件与大气接触周长增加而增大,环境相对湿度变化对混凝土收缩效应较徐变效应更大。
According to the mechanism for the concrete shrinkage and creep,the paper analyzes the main influential factors of the concrete shrinkage and creep,and proves by the analysis result that the creep coefficient and shrinkage strain increase along with the additional contact perimeter of components and atmosphere and the environmental relative humidity changes has larger effect on the concrete shrinkage effect than its effect on creep effect.
