| Abstract: | The parameter of a kind of viscous damper is obtained through pseudo-dynamic test, and the passive control shaking table experiment of a double-layer reticulated shell with some bottom chords replaced by the dampers are carried out, in which several earthquake ground motions of different magnitudes are input. The result indicates that the vibration of the shell with dampers is obviously reduced compared with that without dampers. And the comparison of the experimental result and the theoretical simulation is made, from which good consistence is shown; earthguake reduction factor. |
