摘　　要：单层鞍壳结构的振型分布十分密集 ,振型之间的耦联比较严重 ,因此 ,是否所有形式的单层鞍壳均适宜采用TMD进行减振控制 ,针对这一问题 ,在水平地震作用下 ,选取工程常用的两向正交抛物线型、压斜杆直线型、拉斜杆直线型三种单层鞍壳进行了较为系统的研究 ,得出了一些实用性结论。The vibration mode distribution of a single layer saddle latticed shell is very intensive with heavier couplings between the modes.In order to make a vibration control,can a tuned mass damper(TMD)be used for all types of the single layer saddle latticed shells?In light of this problem three single layer saddle latticed shells of two way orthogonal parabolic,compression and tension diagonals linear types that are often used for projects are studied systematically under actions of horizontal earthquakes,from which some practical conclusions are obtained.
