Numerical Simulation Analysis Of Self-anchored Suspension Bridge's Load Response

The appearance of self-anchored suspension bridge incarnate clearly that people's glory and practical eager of bridge.In consideration of anew acquainting with the self-anchored suspension bridge's merit and applicability, posture develop fast with a rush at home and abroad over the years.This paper taking WanXin Great Bridge of FuShun as an example,with the large-scale finite element software Ansys to establish a complete full-bridge finite element simulation model,which focused on analysis of the self-anchored suspension bridge's bridge alignment adjustment,static, dynamic characteristics and the impact of load factors.The paper using Midas civil's solution of the initial cable force of main cables and slings, import to Ansys simulation model for the adjustment of the expectation bridge state, have got the more reasonable cable force of the main cable and slings. According to CJJ3737-90, calculate the structure's internal force of the arrangement carry of dynamic automobile load, then give the vibration characteristics analyses. Use time course analysis for the simulation analyses of seismic loading, vehicle dynamic load and the coupling of them, then give the comparison of the dynamic effect of the car-load.Based on vehicle dynamic load factors,comparate the simulation analysis by introduction of different cosine cycle, driving speed, and through self-anchored and anchored two different forms.The using of some ideas and methods of the finite element software for how to build, amend, adjust, calculation, analysis and research of self-anchored suspension bridge simulation model. present definitely reference value for uniformity type bridge's design, construction and health detection.
