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. 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。
The combination of previous and present papers has established the theory and method for working out relaxation and retardation spectra and other viscoelastic functions from dynamic mechanical temperature spectrum at a constant frequency. 综合我们的研究结果,可从一个固定频率下的动态力学温度谱求得聚合物的松弛时间谱及其它粘弹函数。
A study on continuous retardation spectrum of mass concrete 大体积混凝土连续阻尼谱函数研究
A new method for working out relaxation and retardation spectra and other viscoelastic functions from the dynamic mechanical temperature spectrum and a_T ( T) directly has been established. 建立了一种从动态力学温度谱和αT(T)直接求松弛谱、推迟谱及其它粘弹函数的新方法。
