| Abstract: | Seismic control of long span space trusses has been the focus of attention for the civil engineers. The anti-earthquake performance of the structures has a direct effect on the people＇ s life and economic safety. This paper utilizes the viscoelastic dampers to control the seismic vibration of long span space trusses. The mechanical parameters of the viscoelatic dampers are calculated and vibration responses of a certain truss with and without viscoelastic dampers are compared to assess the anti-earthquake performance of the structure with viscoelastic dampers. According to the calculation results, the seismic responses which include acceleration, displacement and inner force are obviously decreased under both Taft and E1 Centro earthquake wave. The vicoelastic dampers in the truss dissipate much of the input earthquake energy. |
