| Abstract: | In this paper, vibration reducing analysis was carried out for K8 single- layer reticulated domes in which all horizontal pin supports were replaced by spring supports. The differences of the frequencies between uncontrolled and controlled structures were studied in order to illustrate the vibration reducing mechanism of the reticulated domes. The vibration reducing effects were compared under frequent earthquakes. The results indicated that vibration reducing technique can control the reactions of the reticulated dome effectively. |
