| Abstract: | The paper introduces the simplified calculation model of the grillage beam of the multiple skew girder bridge, analyzes and sums up the influential law of parameter on the dynamic features and seismic response of the multiple beam skew girder bridges, and proves by the studies that the seismic responses of the continuous girder beam can be reduced by improving the stiffness eccentricity ratio and frequency ratio. |
