| الوصف: | Since structural damage by fire in modern Reinforced Concrete (RC) structures causes significant loss of human life and property, it is important to evaluate the residual capacity of fire-damaged RC structures exposed to high temperatures. In this study, the behavior of fire-damaged RC frame structures (single-bay & three-bay frame), considering non-mechanical strain, was investigated by applying numerical analysis. The behavior mechanism was analyzed by numerical results of the single-bay frame and similar behavior was observed in each member of the three-bay frame. Principally, regarding the three-bay frame structure, the time of fire-resistance was evaluated under various fire scenarios, which included symmetrical and asymmetrical fires within the structure. The results of numerical analysis showed that, as the story load action on the structure increases, the fire-resistance time decreases. Finally, asymmetric fires should be considered for safety assessment against fire because the fire-resistance time under asymmetric fire conditions is shorter than that under symmetric fire conditions for all load conditions. |
