| Abstract: | According to the structural characteristics of thin-walled box girder structure and theory of constrained torsion, which is on calculating the constrained torsion of thin walled box beams, the formula for calculating the positions of their torsion centers is presented in this paper. Compared with examples, the formula proves to be accurate, and can be used easily. More over, it can be applied to practical projects. |
