摘要
提出了可应用于中低层和多高层隔震结构的近似实空间解耦方法.利用强迫解耦法、Kelly法和近似实空间解耦法对具有非经典阻尼特性的隔震结构进行了对比分析,并将结构位移响应用具有明确物理与工程意义的系列二阶标准振子位移响应与速度响应线性组合来表示.通过理论分析和算例求解可知:近似实空间解耦法具有很强的优越性和很高的计算精度,结构隔震层和顶层的位移响应最大误差仅为0.361%和1.444%,可推广应用于隔震结构的动力响应分析.
Approximate real space decoupling method applied to the lower-middle level and high-level isolated structure was proposed.Forcing decoupling method,Kelly method and approximate real space decoupling method were used to compare and analyze isolated structure with non-classical damping characteristics.The method of using with clear physical and engineering significance series secondorder standard vibrator displacement response and speed response linear combination to express the structural displacement response was set up.The approximate real space decoupling method has strong superiority and high calculation accuracy which is shown by theoretical analysis and case solving.Isolation layer and top structure′s displacement response maximum deviation only is 0.361%and 1.444%respectively,which can be applied to isolation structure dynamic response analysis.
