Abstract
We present a nonlinear mathematical model for numerical analysis of the behavior of concrete subject to transient heating according to the standard ISO fire curve. The mathematical model consists of the balance equations (conservations laws) with boundary and initial conditions, constitutive laws and material data for concrete at high temperatures. The numerical algorithm based on finite element method for the numerical solution of the energy equation and finite difference method for the mass balance equations is presented. Distributions of temperature, saturation of water and water vapor pressure are demonstrated.
