Abstract

Purpose. Based on the developed comprehensive methodology for calculating the fire resistance limits of modern building structures made of reinforced concrete, obtain tabular data on the assessment of the fire resistance of reinforced concrete walls, columns, beams and slabs, taking into account the presence of an air cavity, concrete class, type of aggregate, prestressing reinforcement, and also the presence of constructive fire protection based on fire-resistant gypsum boards and fire-resistant suspended ceilings.

Methods. Analysis and generalization of the results of calculating the fire resistance limits of reinforced concrete building structures according to the methodology developed on the basis of experimental (laboratory and fire, including full-scale) and theoretical studies.

Findings. The rules have been developed for determining the fire resistance limits of modern building structures made of reinforced concrete, based on the simplified use of tabular data, which make it possible to ensure the fire safety of buildings and structures by assessing the fire resistance limit of unprotected reinforced concrete building structures and selecting the parameters of structural fire protection to increase it.

Application field of research. The results obtained can be used in the development of standards for the design and construction of reinforced concrete structures, for solving problems of assessing the fire resistance of building structures and elements in the design and construction of buildings and structures, including within the framework of existing standards.
