    Abstract ( )   PDF (237KB) ( )  
    Generally a diaphragm is set between the rof of the pier and the mid-span in order to enhance the rigidity refers to the bend-resistance of the box-beam structure in the same direction with the bridge and the twist-resistance cross wise.However,near the diaphragm section,the diference of strength function is obvious comparing to the convention section,which is usually be ignored during the design process.Taking the rof-board crack near the pier of a bridge for example,the diaphragm 's influences on the mechanics function of the roof-board are analyzed specifically.The results show that the strength situation is obviously different between the rof-board around the diaphragm and those section far away from it.
