| Abstract: | The strengthening technology of the prestressed composite tress with tougong web members bars was used in the multi-storied factory building. In this paper, the parameters of the vibration frequency, the vibration speed and accelerating of the floor under the vibrating loads were tested and compared between the strengthening floor and original one. The results indicate that the discussed strengthening technology is effective and valid. It is valuable for the engineering reference. |
