摘要

在一个１：４的五层模型刚架结构上进行了变阻尼半主动结构控制振动台试验．在结构的底层安装了一个溢流阀式变阻尼控制器，输入几种不同的地震动并采用几种不同的控制算法对结构进行了变阻尼半主动控制。振动台试验结果表明，受阻尼半主动结构控制仅需要很少的电能，就可以达到较好的控制效果，是一种很有应用前景的结构振动控制方案。结合溢流阀式变阻尼控制器的特点，分析了一些因素对控制效果的影响．
A semi-active structural control shaking table experiment was performed on a five story 1:4 steel frame model structure. A relief type variable damping controller was installed on the first floor of the model structure. Different kinds of seismic excitation were used as inputs and several semi-active control algorithms were used to investigate the performance of the active variable damping system. The shaking table test demonstrated that the semi-active structural control with variable damper is a promising structural control strategy for it is very effective on response reduction and it consumes only a small amount of electric power. Considering the characters of relief type variable damping controller, some factors that affects the control performance were analyzed in the paper.
