摘      要：This paper presents the first of a series of studies on the seismic design of high-rise towers for cablestayed bridges under strong *** practical cable-stayed bridge with a 730 m long main span and two high-rise towers over 200 m in height was selected for this *** preliminary results show that compared with piers,the tower is more vulnerable to pulse-like earthquakes,and it may develop plasticity at certain *** addition,viscous dampers may not have the same effect during pulse-like earthquakes as they do under site-specific ***,reoptimization of damper parameters or reconsideration of other energy dissipation devices will be needed if strong earthquakes are likely to occur.
