This project takes Wuhu Yangtze River Highway Second Bridge as an engineering example. In view of the structural and seismic characteristics of the new structure such as the super-long-span sub-limb column tower cable-stayed bridge and the oblique damping system, the partial precision modeling is applied to the seismic vulnerable components such as sub-limb column tower and pier on the basis of the seismic finite element model of the space bar system. In addition, the correct and reasonable finite element simulations of the important components and seismic construction measures such as cables and oblique dampers, are carried out by adopting the elements and constitutive relationships suitable for structural seismic analysis. Meanwhile, the material nonlinearity and geometric nonlinearity of super-long span bridges can be considered and nonlinear seismic finite element model of super-long-span column cable-stayed bridges is established.
