This paper presents another explaination of why the four steel box girder bridges in the world were damaged in 1969-1971。It is pointed out that the boundary conditions adopted in calc-ulating the buckling load of the compressive plates of box girderbridges are quite different from their actual boundary conditionsand that this difference is the primary cause led to such failureof these bridges as mentioned above,because the ultimate load ofthe compressive plate of box girder bridge determined accordingto its actual boundary conditions is less than the buckling loadadopted in the design of the bridge.This paper makes a point thatonly when the analysis of the ultimate load of the box girder isworked out,then its correct design may be obtained.In thispaper an approach to the space analysis with respect to the ulti-mate load of steel box girder bridges is given as a mathematicalmodel.
