Analysis of Traveling Wave Effect on Half-through CFST Arch Bridge by Large Mass Method Jun Ma1, a, Yan Li1,b 1 School of Transportation Science and Engineering, Harbin Institute of Technology, Harbin, China amajunlxd@163.com, bliyan_2007@126.com Keywords: Traveling wave effect, Large Mass Method, CFST material, Half-through arch bridge, Seismic response Abstract.
The nonlinear characteristic of material could also be considered so that the results could be closed with the real response.
With this equation, the seismic analysis could take the traveling wave effect and material nonlinear characteristic as considerations.
