Abstract

Nowadays, there is a need for inspection, assessment of the technical condition of reinforced concrete structures and restoration of serviceability of existing reinforced concrete structures after exposure to high temperatures. At the same time, the problem of ensuring long-term and reliable operation of building structures after power and high-temperature influences due to the adoption of appropriate materials or protective measures remains unresolved. The paper presents experimental studies of reinforced concrete beams at high temperatures. The most promising way to verify the data of experimental studies is computer modelling of structures, including during a fire. The proposed technique allows you to effectively predict the residual life of reinforced concrete beams, increase human safety, ensure the safety of material values.
