| Abstract: | 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. |
