A present LSD(limited state design) code for bridge temperature load have applied a uniform standard for various bridge type. In this study, in order to acquire the calculation effective thermal, a steel box girder bridge section specimen with real size dimension was manufactured. And over a year, the temperature data were measured in the sections. Effective temperature within the cross section according to atmospheric temperature were calculated by this experiment data. The analyzed results was very similar correlation when compared with the effective temperature of the Euro Code. Therefore, the effective temperature which calculated based on the present data could be used as the basic data in order to present to the appropriate design criteria for the thermal loads on the domestic bridge design
