Seismic Research of Continuous Rigid Frame Bridge under Cantilever Construction Method
To research the effect of earthquakes of different magnitudes on continuous rigid frame bridge under cantilever construction method, combined with the newly promulgated seismic design rules of highway bridges in China, finite element model has been built by Midas software by using the response spectrum method and dynamic time history analysis method to analyze cantilever construction method of the various stages of seismic response analysis. The results indicate that the bending moments of root segments of cantilever beams and the bottom sections of piers change greatly. So it should be attached importance to in design.
