Abstract :
    Concerning fire and fire is one of the fundamental issues in the design of reinforced concrete structures. Concrete in terms of structure and composition, and due to the low thermal conductivity and non-combustion capability in fire conditions, is a suitable behavior for analyzing and Cross sectional design of reinforced concrete structures Common tools called interactions diagrams are often used to communicate the final values ​​of bending anchor and axial force, and using these diagrams, a quick estimate of cross-sectional behavior can be expressed. Therefore, although much research has been done in this field, further study is needed in this field, and the impact of several parameters on the behavior of hot concrete should still be investigated. In this paper, the purpose is to develop a concrete model that reflects the actual behavior of fireproof concrete buildings. This model should have a fully hydrated thermal-mechanical coupling, combined with complex structural analysis, including transient strain effects.
