【Abstract】 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.更多还原
