Analysis of Deflection Parameter of Extradosed Cable-Stayed Bridge |
| |
| Abstract: | The control and influencing factors on deflection of extradosed cable-stayed bridge are calculated and analyzed with finite element software.Influence degree of unit weight of concrete,tension of stayed cable,construction load and shrinkage creep on extradosed cable-stayed bridge is obtained,providing reliable data to determine precamber reasonably. |
