摘要
通过对混凝土粘弹性相的任意徐变度函数C (t-t′)进行Laplace变换 ,导出了混凝土材料的连续阻尼谱函数 ,可以使Bazant ,Z .P .固化徐变模型适合于具有任意徐变规律的混凝土材料 ,避免了Bazant算法中根据经验选择阻尼时间的做法 .
Based on the Laplace Transformation of the visco elastic creep of concrete, a continuous retardation spectrum is deduced. It makes the solidification creep theory suitable for concrete with different creep mode. By using this method, the trail and error in choosing the first retardation time in Bazant algorithm method can be avoided.
