Effects of traveling wave to seismic response of long span rigid-framed bridge

HUANG Xiao-guo1,HU Da-lin2,ZHANG Hou-ju2(1.State Key Laboratory for Disaster Reduction in Civil Engineering,Tongji University,Shanghai 200092, China;2.School of Highway,Chang'an Universtiy,Xi'an 710064,Shaanxi,China)  
The advanced finite element analysis program ANSYS/TRANSIENT is successfully used in numerical simulation of seismic response of rigid-framed bridge to traveling wave exciting from three dimensional orthogonal components acting individually or jointly.It is studied to the effects of traveling wave in different direction and phase lag.The general influence of traveling wave in the long span rigid-framed bridge is obtained: when considering single or three dimensional traveling wave,the internal force of structure increases in the different extent and the natural period becomes longer,however,the structural displacement decreases.5 tabs,7 figs,13 refs.
