Calculating Fire Resistance of Non-Standard Cross-Sections of Elementsof Reinforced Concrete Structures Using the Ansys Software Complex

Abstract

The article considers mainelements of cast-in-placereinforced concrete structures: slabs, beams and columns.Theirbehavior under temperature conditionsof a standard fire has been studied. As an example structures of the International Medical Center in Moscow, Western District, the territory of the Innovation Center "Skolkovo"were considered. The software Ansys Workbenchwas usedfor calculation of structures. According to the results of the thermo technical calculation, graphs of temperature distribution over the section height of the elements as a function of heating time are plotted and an assessment of fire resistance based on the criterion of loss of heat-insulating properties is proposed.
