Abstract

The dynamic analysis of cable-stayed bridges in seismically active regions is potentially important to highway facilities design. A quite general nonlinear dynamic analysis is developed for a realistic prediction of tower seismic performance of cable-stayed bridges. One of the most important decisions in carrying out proper analysis is to select a design earthquake that adequately represents the ground motion expected at certain site and in particular the motion that would drive the bridge structure to its critical response. So an extensive series of seismic response analyses using a wide range of ground motions are carried out. The ductility demands and base shear demands due to near-fault and long duration ground motions are compared. The stipulation of code standard input excitation limitations and the present calculated demands are discussed.
