The British specifications and Japanese specifications are often referred to calculate effective flange width in order to analyze shear lag effect of steel box girder. However, there are some differences between the two specifications. According to the two specifications ,the effective widthes of a simple supported bridge, a continuous girder bridge with two spans and a continuous girder bridge with three spans are discussed. From the results, we can draw the conclusion that it is pessimistic
more » ... it is pessimistic and simple to calculate effective width of simple support beam according to Japanese specifications.The wide span ratio is the key factor for effective width of box girder bridge in British and Japanese specifications. It is more accurate to calculate the effective width of box girder bridge with British specifications. The shear lag and effective width Longitudinal bending moments would cause shear force of thin-walled box girder at the flange and web joint. Because of the shear force, the normal stress of at the upper and lower flange along the International Forum on Energy, Environment Science and Materials (IFEESM 2017)
