【摘要】 以框架填充墙结构中的填充墙作为TMD系统中的质量块,通过在结构中布置多个填充墙TMD形成MTMD减震系统。为了研究该新型减震结构中TMD布置及连接参数的设计方法,基于结构受控振型及MTMD系统固有频率线性分布的假定,建立了填充墙MTMD结构的理论分析模型,由积分变换给出了传递函数。通过传递函数分析,给出填充墙MTMD结构中TMD的连接参数的计算方法。针对优化设计目标,设计了结构振动台试验的模型试件,振动台试验研究结果表明,结构设计参数优化后,减震效果较为显著。更多还原

【Abstract】 In the structures the in-filled walls are taken as mass blocks in Turned Mass Damper(TMD) systems.Several in-filled wall TMD devices are settled in structures so that the MTMD(Multi Turned Mass Damper) vibration absorption structures are formed.In order to study the location of TMD and design method of connection parameters,the theoretical analysis model of in-filled wall MTMD structure is established based on the controlled vibration type and the assumption of the inherent natural frequency linear distribution.And then the transfer function is given by integral transform.By analysis of the transfer function,the calculation method for the connection parameters of TMD in in-filled wall MTMD structures is obtained.With the aim of viewing the optimum design objective the shake-table test model is designed.The results of shake-table test indicate that the vibration absorption effect is remarkable after the structure design parameters are optimized.更多还原
