| Abstract: | This paper presented vibration energy dissipation design of the large-span floor structure.TMD system and fluid viscous dampers were installed in the middle span of steel beam located.A TMD system includes a mass of metal and 4 spring dampers.The fluid viscous damper is a kind of velocity related damper without rigidity.The dynamical analysis and computation results prove that the vibration energy dissipation can effectively reduce the resonance response of the large-span floor structure.All cases of the me... |
