An Analytic Method for the Residual Strength Evaluation of Fire-Damaged Reinforced Concrete Beam

摘要: This study is to get the proper evaluation of residual property reinforced concrete beam exposed fire. focused on strength resistance and analytical RC members high temperature. And this basis research conduct other studies. To analysis by finite element method, Total-RC program was used it Total-Temp also temperature distributions at section. All results were compared with pre-existing experimental data simple supported beam. Using it, parameters influencing structural capacity temperature-damaged estimation are investigated. The distribution section calculated in step. An application method heating test result for which subjected ISO 834 as follows; 1) loads-displacement relationship beam, considering initial thermal stress cross heat transfer estimated comparing value results. 2) time (0, 1, 2 hours), show that load exposing fire affected.
