Abstract
Depending on the risk of fire associated with a building, they must meet some minimum requirements associated with a level of fire stability. Usually, a tabular method is used to check concrete elements, but this method does not give information about the load-bearing capacity in case of fire. Determining the load-bearing capacity is a laborious process that requires knowledge of the temperature distribution in the section. Starting from the observation that the isotherms provided by Annex A of SREN 1992 are defined only for a limited number of cases and do not explicitly take into account the concrete cover, an analysis of the temperature distribution a was performed for a section of reinforced concrete column in the absence of reinforcement but also for two variants of the concrete cover. Using the results of the thermal analysis, it was analyzed how to modify the load-bearing capacity of a reinforced concrete column under the conditions of exposure to standard fire, for 90 minutes.
