| Abstract: | The deflection differential equations of thin-walled box-girders are established based on considering the influence of shear lag on the deflection of box-girder, and the deflection present analysises under uniformly distributed load and concentrated load and the most deflection calculation formulas in span are give. Numerical results that the method proposed in the paper gives utility and accurate solutions with the design and construction control of box-girder bridge. It can be very widely used in civil engineering. |
| Keywords: | bridge engineering thin-walled box-girder shear lag deflection |
