| Abstract: | With the development of earthquake protective system, the anti-seismic ability of long span bridge could be enhanced. In anti-seismic ability design, Longhua Songhua river bridge in JiLin province will use lock-up devoice and fluid viscous damper that appears in recent years. This paper sets up the model and equation of long span bridge using lock-up devoice and fluid viscous damper in multi-supported excitation's seismic analysis. With the dynamic time history analysis, it makes Longhua Songhua river bridge's seismic response analysis and discusses the influence to long span continuous box-girder bridge with using new earthquake protective system. |
