Seismic Research Of System Parmeter Of Earth-anchored Single Tower Cable-stayed Bridge

Anchor block mansard single tower cable-stayed bridge is a new type of structure of cable-stayed bridge, it has novel structure and unique, it also has good landscape.In this paper, the Bridge has the first structure so far in China- ChengDe TaiPingZhuang bridge,as the engineering background. Using of Midas/civil build different finite element calculation model of bridge, and compare the different structure form of cable-stayed bridges.The paper first introduces the characteristics of single tower cable-stayed bridge, then,introduces the anchor and anchor characteristics of cable-stayed bridge, and briefly introduces the general principle of calculation model in this paper. According to the background of practical engineering that using Midas/civil to establish the whole bridge finite element space model, and on this basis, analyzing different forms of bridge tower cable-stayed bridge with mechanics behavior of the whole structure. Paper also using Midas/civil to analyze different angle of the bridge tower cable-stayed bridge, different anchoring of tower cable-stayed bridge, cable-stayed bridge without back cable.
