摘　　要：本文将粘弹阻尼器引入网壳结构,针对网壳结构粘弹阻尼器减振系统,编制了有限元分析程序,利用该程序对单层球面网壳和单层柱面网壳进行了大量的减振分析。计算结果表明,粘弹阻尼器减振系统对大跨网壳结构的减振效果是十分明显的,是一种适合大跨网壳结构的减振系统。A vibration reducing system of viscous-elastic damper is introduced into reticulated shells. A finite-element analysis program of the vibration reducing system for reticular shells with viscous-elastic dampers is developed. Lots of numerical calculations of vibration reducing for single-layer reticulated domes and vaults by the program are carried out. It is proved by numerical results that the vibration reducing system of viscous-elastic damper is suitable to reticulated shells, furthermore, its effects of vibration reducing are excellent.
