Özet
When designing load-bearing reinforced concrete components, external factors such as fire should be taken into account in addition to horizontal and vertical forces. Parameters such as cross-section of the reinforced concrete components, concrete cover, material properties and quantity of the concrete steel affect significantly the fire resistance of the reinforced concrete section exposed to fire. In this study, optimal cross-sections are obtained for 30, 60 and 90 fire duration taking into account the different cross-sections and concrete cover of the reinforced concrete column. The method for calculating the optimal sections of reinforced concrete columns is the modified metaheuristic algorithm, which is a combination of Flower Pollination Algorithm (FPA) with Jaya Algorithm (JA). The behavior of reinforced concrete column in case of fire is investigated according to EN-1992-1-2 (Eurocode 2: Design of reinforced concrete structures-Part 1–2: General rules—Structural fire design). The Eurocode offers 3 different methods for the fire design of concrete structures (simplified, advanced calculation methods and the tabulated date). In this study, optimal results are obtained in the tabulated date section. Thus, some limitations in EN-1992-1-2 such as minimum reinforcement cross-sectional area and column buckling length have been overcome. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2023.
