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

Based on the theory of stochastic finite element, the structural parameters of frame - shear structure including stiffness and mass and damping are simulated to be stochastic variables. by solving recurrence equation of stochastic finite element, the duration curve of mean value and standard deviation of seismic response can be obtained for every floor of frame - shear structure. an analysis is thus given to the effects of independent variation and simultaneous variation of structural parameters on the seismic dynamic response of frame - shear structure. as shown by the results, with regard to frame - shear structure, the effect of variation of strucural parameters on the change of mean value are chiefly the increase of standard deviation of response. variation of stiffness will cause the response of frame - shear structure to variate greatly ; variation of mass shows less effect ; and variation of damping shows insignificant effect. the effects of simultaneous variation of various structral parametres on seismic response are only slightly greater than the effect of stiffness variation alone
