混凝土阻抗谱的解析表示

Analytical Expressions of Impedance Functions of Concrete

提出了确定混凝土阻抗谱解析表达式的普适方法．考虑到混凝土阻抗谱具有分数幂次的特点，从混凝土阻抗谱的Ｂｏｄｅ模图出发，以实验曲线渐近线的斜率及其变化来确定阻抗函数的各个因子，从而可以确定其解析表达式．

Based on the Bode's plot of modulus, a general method to find the analytical expression of impedance function of concrete has been proposed. The slopes of the asymptotes of the experimental curves are important in the determination of the factors in the analytical expressions. Examples are given to show how to use the method.
