Elastic-Plastic Damage Model to Predict Pore-Pressure Effect on Concrete Behavior at Elevated Temperatures
Excessive internal pressure and high temperature are the key reasons for concrete spalling, and there are complex interactions between these two aspects. In the current research, a theoretical model to predict the pore pressure effect on concrete behavior is developed. The temperature effect on concrete is incorporated to estimate the change of pore pressure. In order to obtain the pore pressure accurately, volumetric deformation and damage-related permeability are considered to predict the pore pressure in concrete for both tension and compression. The concrete mechanical behaviors are simulated considering pore pressure effect. The predictions agree well with the experimental results. The deterioration of concrete at elevated temperatures and after heating is predicted; it shows that spalling behavior can be simulated by the developed model with reasonable accuracy.
