Retracted: Research on Key Techniques of Transverse Seismic Design of Poyang Lake Highway Bridge II

The main bridge of Poyang Lake highway bridge II employs the scheme of a five-span
$(68.6+116.4+420+116.4+ 68.6=790)\ \mathbf{m}$
composite beam cable-stayed bridge with two pylons and two cable planes. In this paper, the finite element modeling is used to conduct the seismic analysis, the problems to be solved in transverse seismic design are studied without changing the existing bridge structure, several measures are put forward and compared, finally, it is decided that a transverse elastic cable should be set between the tower and beam, which can be recognized as a technological innovation to a certain degree.
