The economy and efficiency of the diaphragm part has been highly demanded in steel box girder bridge design. In this study, experimental tests were performed to measure both temperature and stress distribution of the diaphragm part in a 4 span steel box girder bridge which was under constructions.
By carefully analyzing the results, the temperature loads were determined with a numerical formula. Also, the proper length of the vertical stiffener was presented here.
And the determined temperature distribution and the proper length of the vertical stiffener were compared with the results of FE analysis. Then the temperature loads presented here were different from EURO code. And the proper length of the vertical stiffener was similar to ones of previous studies
It was thought that the studied results could provide the basis for an economical and efficient design of the diaphragm part of steel box girder bridges and for the classified temperature loads in bridge design.
