Travelling Wave Effect Analysis of Long-Span Cable-Stayed Bridge
The vertical distance is generally greater of long-span cable-stayed bridge, while the velocity of seismic wave propagation is certain, therefore, the incentive suffered of long-span cable-stayed bridge’s pier is not the same time, but there is a certain time interval. Currently in the bridge designs, seismic response analysis is numerically based on coincident earthquake excitation, so that the actual results are different from the results of obtained widely. Based on the analysis of the traveling wave effect to the long-span cable-stayed bridge under the assumption of seismic waves, there are a series results of the bridge control point displacement, the maximum internal force of the earthquake response, and through these results, conclude some effective conclusions.
