Generally ship lift structure is consisted of two or four huge reinforced concrete tube towers and a single - story machinery building on the top of tube towers. because the tube towers is demanded to support the large loads, the lateral stiffness of tube towers is a few hundred times as solid as that of the top machinery building and cause the sudden change of the stiffness. this change would cause insentive seismic whipping effect of the top building. the aseismic methods are difficultly used to reduce seismic responses of the top building of ship lift structure. the feasibility of develop an intelligent vibration control system is explored in the paper
這樣，在塔柱頂部鋼筋混凝土平臺就會產生側移剛度的突變。這種巨大的剛度突變會引起升船機頂部廠房強烈的地震鞭梢效應，使得升船機頂部廠房地震反應的控制就成為升船結構抗震設計中的關鍵問題之一。由於採用常規的結構振動控制方法難以較好地解決升船機頂部廠房地震鞭梢效應，因此這就為智能振動控制技術的發展和應用提供了可能。 -
