초록/요약
Inconsistent damages over the surface of structural members are expected from a compartment fire situation, which may cause additional reduction of structural performances especially in the case of reinforced concrete (RC) columns. In this study, an analytical modeling method for simplified cross section was proposed and validated for the prediction of axial strength of fire-damaged RC columns. The proposed modeling method was subsequently used to develop interaction diagrams of fire-damaged RC columns with varied heat exposure areas. Compared to the experimental results, it was found that the P-M interaction diagram allowed estimating axial force and moment capacities of the fire-damaged concrete columns.
