This study is to get the proper evaluation of the flexural strength of reinforced concrete members exposed to fire. An analytical method is presented for the moment-curvature relationship to the cross section which is subjected to heating and boundary conditions in various reinforced ratios. This method use heat-transfer analysis for the cross section as well as the stress-strain models and thermal properties of normal strength concrete and reinforcing steel with high temperature. The results of this study are as follows: 1) The stress-strain relationships of concrete and reinforcement, which is considered with initial thermal stress of cross section and heat transfer analysis are estimated. After comparing analytical value with experimental result about maximum moment of members, its average(analytical data/experimental data) shows 0.96 and we proved trust-ability about proposed analytical method. 2) The specimens showed various failure modes following to the reinforcement ratios and heating conditions. At the same heating conditions, the higher reinforcement ratio, the lower the resistance load and initial stiffness of beam members. The values which are compared with the nominal strength and experimental result to the maximum load are 0.75-0.95 at 700℃. Strength reduction of concrete lead to flexural failure mode in the high temperature. 3) The results of analysis with parameters are that the flexural strength exposing at high temperature is affected by the heating times(0, 1, 2, 3 hour) and thermal stress at the restrained condition of deformation. An influence of concrete cover depths(3, 4, 5, 6 cm) are relatively small to strength reduction in the section of the support region.
