| Abstract: | By dynamic test on an advanced large shaking table and three dimensional finite ele-ment calculation for shiplifter tower structure of the Three Gorge project, not only the dynam-ic characteristics of shiplifter tower structure, such as natural frequency, vibration shape anddamping ratio, but aIso the seismic responses of shiplifter tower structure to the designearthquake have been investigated. Based on the revised edition of " Specifications for SeismicDesign of Hydraulic Structures" in China, the seismic safety of the shiplifter tower structure ofthe Three Gorge project and the maximum earthquake relative displacement of the towers whichinfluence the operation of engine room are evaluated. |
