RESEARCH ON A DYNAMIC CONSTITUTIVE MODEL OF CONCRETE IN HIGH TEMPERATURE

摘要：

Based on ZWT visco-elastic constitutive model and damage evolution of concrete submitting Weibull distribution,the damage thermo-visco-elastic constitutive equation at high strain rates is proposed.Through numerical fitting,the parameters of the constitutive equation are obtained.A comparison between model prediction and experimental results show that both of them agree well with each other.
