采用半主动摩擦阻尼器进行建筑结构综合振动控制和健康监测(1):方法论

对建筑结构振动控制和健康监测受环境影响的程度进行研究。由于很多研究将振动控制和健康监测分别独立来考虑,因此,提出综合程序,采用半主动摩擦阻尼器对建筑结构的振动控制和健康监测进行分析,并首次引进了综合系统的概念。基于已知刚度,采用半主动摩擦阻尼器提出了修正刚度、质量矩阵和识别结构参数的计划。根据修正的系统矩阵,对带有Kalman的过滤器,采用局部反馈控制的半主动摩擦阻尼器并对其控制性能进行研究。假定建筑在突发事件和长期使用过程中遭受了一定的破坏,采用已识别的原始结构参数,基于已知的刚度,采用半主动摩擦阻尼器提出损坏监测计划。所提综合程序的可行性和精确性,在本文的第二部分进行了论证。

Integrated Vibration Control and Health Monitoring of Building Structures Using Semi-Active Friction Dampers:Part I-Methodology

Vibration control and health monitoring of building structures subjected to harsh environments have been actively investigated in recent years . Nevertheless ,in most investigations the two aspects have been treated separately . This paper presents anintegrated procedure for vibration control and health monitoring of a building structure using semiactive friction dampers . The concept of an integrated system using semiactive friction dampers is first introduced . A scheme based on adding a known stiffness b...
