| Abstract: | Through analyzing the high temperature field of the profile of a reinforced concrete beam simply supported at both ends and the thermal mechanical behavior of material in a fired field,the profile is divided into an elastic zone and a plastic zone,and then the strength of the concrete in different zones can be obtained.The calculating formulae of the concrete stress and the ultimate load of the beam are established.In the computational example,the temperature field and the changing rules and causes of the ultimate load are analyzed. |

| Keywords: | fired field reinforced concrete beam elastic zone plastic zone ultimate load |
