【摘要】 国际上大多被动、主动和半主动控制都是基于结构的动力特性设计的。然而,对于建造于软弱地基上结构,土-结构相互作用(SSI)效应比较强烈,致使土-结构相互作用体系的动力特性发生改变,而这种改变将在很大程度上影响结构振动控制的效果。因此,在结构振动控制设计时,需要定量地考虑SSI的影响。首先,综述了考虑SSI效应研究结构被动控制、主动控制和半主动控制的进展。接着,广泛地评述了考虑SSI效应研究不规则建筑振动控制的进展。接着,建议了考虑SSI效应研究不规则建筑半主动控制的展望。最后,指出了考虑SSI弹性和弹塑性不规则建筑基于支持向量机半主动控制的研究前景。更多还原

【Abstract】 Intensive soil-structure interaction(SSI) effects for structures built on soft soil give rise to the perturbations in their dynamic characteristics,which will significantly deteriorate the effectiveness of structural vibration control.Therefore,there is a need of quantitatively including SSI into consideration in the design of structural vibration control.An overview was rendered on the studies of the passive,active,and semi-active control for structures considering SSI effects.A comprehensive survey was given on the earthquake vibration control for asymmetric buildings with consideration of SSI.Then the future directions of semi-active control for asymmetric buildings were proposed taking SSI into account.Finally,the support vector machine(SVM) based semi-active control was highighted on both the elastic and inelastic asymmetric buildings including SSI effects into consideration.更多还原
