| Abstract: | With the lower tower cable-stayed bridge of bddge span arrangement（90＋ 165 ＋ 165 ＋ 90）m as an engineering example,the article described the derivation process of ca- ble/beam live-load ratio formula, and used the spatial finite element program MidasCivil2011 to establish the structural finite element model, calculated and analyzed the impact of cable/ beam live-load ratio changes of lower tower cable-stayed bridge on structural static charac- teristics,and the analysis results can provide the reference for the design of the same type of bridges. |
