| Abstract: | The torque caused by transverse wind pressure and longitudinal displacement caused by various temperature are considered. The design influence factors of the double thin-wall piers are discussed in accordance with analysis of the double thin-wall piers of continuous rigid-frame bridge. On the basis of the nonlinear programming, SUMT is applied to optimize the double thin-wall pier parameters. |
