Stress-stain state of elements of building structures in fire (English)
0 references
In terms of the finite element method, a mathematical model is proposed for a quantitative description of deformation processes in building structures and their elements in fire conditions. The Lagrangian approach is used to determine the stress-strain state of a body under force and thermal loading. The proposed approach is verified by solving a number of test problems. The convergence of numerical solutions for these problems is investigated. The numerical results obtained under various model assumptions are compared with the experimental data and known analytical solutions of similar problems.
