Seismic vibration control of space frame structures with viscous dampers

本研究基于折板型网架结构的减震控制方法和措施,将粘滞阻尼器作为减震元件,利用SAP有限元分析程序,在对网架结构消能减震进行大量分析的基础上,提出阻尼器在网架结构中的合理布置位置的设计建议。计算结果表明:粘滞性阻尼器减振系统对网架结构的减震效果是比较明显的,是一种适合空间网架结构的减震系统。

Viscous damper is introduced into space frame structures. Lots of numerical calcula- tions of seismic vibration control for space frame structures by the program of SAP are carried out. The locations of viscous dampers in space frame structures are advised. It is proved by nu- merical results that the viscous damper is suitable to space frame structures. Furthermore, its effects of the viscous damper are excellent.
