| Abstract: | The calculating model for analysis of continuous curved box girder bridges by plan element computer program is established. The increasing coefficient of section stress accounted to the effect of restrain torsion is introduced. This approximate method may give the calculation results with higher precision.Therefore, it has practical significance for disigners. |
| Keywords: | continuous curved box girder bridge equivalent continuous right beam bridge inceasing coefficient of section stress restrain torsion length of chord |
