摘要

在Penzien模型的基础上，建立了考虑桩-土-结构相互作用（PSSI）的计算模型，推导了其主动控制方程，分析了PSSI对结构控制的影响，以及土与结构各种主要参数对控制效果的影响。分析结果表明：考虑PSSI，结构地震响应有所加大，控制效果有所降低，最大控制力增大；在一定范围内，土的剪切波速、桩的截面惯性矩以及上部结构的基本周期对结构的主动控制有着显著的影响。

Abstract

Based on the Penzien model, the calculation model of structure in consideration of pile-soil-structure interaction(PSSI)is
established and the vibration control equations of structural motion are derived.PSSI’s effects on structural vibration control are analyzed. The effects of every parameter of soil and structures on structural vibration control are researched. The results show that: consider PSSI, the structural earthquake responds is increased,control-effect is reduced,control-force is increased; the equivalent shear wave velocity of soil, rotary inertia of pile and natural period of upper structure have significant effects on structural vibration control to some extent.
