摘　　要：针对超高层结构抗震设计实践,对振型谱的应用、抗震设防分类、弹塑性位移角统计方法、过渡区的设置原则、特征周期的取值方法及最小剪重比调整方法等设计关键环节进行了探讨,归纳总结了超高层结构设计专项审查中针对这些问题的解决思路。Based on the practical seismic design of super high-rise structure,the exploration for the key links of the design is carried out,such as the application of vibration spectrum,the classification of seismic fortification,statistical method of elastic-plastic displacement angle,setting principle of transition region,the method of obtaining numerical values for characteristic period,adjusting measure of minimum shear-weight ratio and so on.The solutions for these questions in special review on design of super high-rise structure are summarized.
