MATHEMATICAL MODELING OF REINFORCED CONCRETE STRUCTURES BEARING CAPACITY IN CASE OF FIRE USING ANSYS MECHANICAL
The results of mathematical modeling of reinforced concrete slabs behavior during fire tests in the standard fire are presented. The aim of this work is to create and test a methodology for calculating the fire resistance of reinforced concrete structures in ANSYS MECHANICAL bundled software. In the model problem of calculating reinforced concrete articulated on two sides of the plates, the critical temperature of the heating of the structure, the time until the loss of bearing capacity, deformation, stress and deflection are determined. The experimental data are compared with computational modeling. Results analysis allows us to justify the applicability of ANSYS MECHANICAL for solving fire resistance problems of reinforced concrete structures.
