Abstract
In order to research on the influence of traveling wave effect on the seismic response of track-bridge system of a large-span suspension bridge,based on the large mass method with multi-point excitation,and taking the dual-purpose suspension bridge-Wufengshan Yangtze River Bridge as the engineering background,a spatial model of track-bridge integrated dynamic calculation is established by ANSYS.The results shows that com-pared with the uniform excitation,the seismic response of the track and bridge of the suspension bridge varies greatly in the low apparent wave speed interval,but not much in the high apparent wave speed interval,and the traveling wave effect increases the stress of the rail of the main bridge especially;the traveling wave effect causes the hysteresis phenomenon of the seismic response of the bridge at the different side symmetric posi-tions.关键词
