| Abstract: | A new pattern cable saddle structure is used in main tower of Zhongshan City Qijiang River Bridge. Main tower segment model test and behavior of concrete are introduced in this paper. Finite element spatial model is established to analyse the model structure. The results show the stress distribution of the tower saddles and draw a conclusion whether the new pattern saddles structure is reasonable or not. |
