| Abstract: | In this paper, by using the finite element analysis software, the FE calculation model of offshore platforms and T-joints under fire is established. Based on the elastic-plastic analysis method, two model of heat-static coupling are analyzed. Using standard temperaturetime curve, the distribution of ambient air temperature is calculated. According to nonlinear stress-strain relationship for carbon steel at high temperature from Eurocode3, the response of platform＇s overall structure, high temperature carrying capacity and destroy mode of T-joints and with different time and distribution of temperature are analyzed. |

| Keywords: | offshore platform T-joints fire response stress-strain relationship |
