Viscoelastic behavior of concrete pile

摘要

Based on constitutive theory of viscoelasticity, the viscoelastic behaviour of concrete pile was investigated. The influence of viscosity coefficient on the stress, displacement and velocity response was discussed. With the increase of viscosity coefficient, the amplitude of stress wave decreases, and the maximum value of the stress wave shifts to deeper position of the pile. In other words,the viscosity coefficient behaves as lag effect to stress wave.
