- Abstract
- Numerical 3D-model of deformation and destruction of concrete composites is proposed based on representation of inhomogeneous medium by combination of interacting continuums. Numerical modeling of deformation and destruction of heated structures such as a hangar made of concrete reinforced with reinforcing steel was carried out. It is obtained that the developed numerical models allow calculating by the method of finite-dimensional particles the characteristics of the non-stationary 3D-behavior of constructions made of concrete composites up to their complete destruction. It has been shown that heating to T = 600 oC practically does not affect the degree of damage for considered construction.
