The first - order perturbation method correct for forcing decoupling method based on perturbation theory is put forward to decrease error ; iii. the complex modal method is introduced into analysis of non - classical damping systems to eliminate error of forcing decoupling method, and improve the complex modal response spectrum, which can apply to design of non - classical damping systems ; iv. for exerting the energy dissipation capability of each device, a two - step optimum method, whose controlling function is extremum expectation of interbedded displacement, is put forward to optimize the number and position of device ; v. the problem of iterative method applied to analyze energy dissipation systems is indicate, and give some primary advice based on pilot study
為改善上述缺點，本文進行了以下的研究工作：在忽略耗能器附加質量的基礎上，推導出適用於耗能減震結構的攝動法，減少振型分解法在迭代計算過程中的工作量，加快計算速度；針對運動方程的強行解耦所產生的誤差，根據攝動法原理，對其進行一階攝動修正；為消除強行解耦振型分解法用於非比例阻尼結構分析時產生的誤差，引入狀態空間對系統進行復模態分析，並改進了基於復模態理論的、適用於非比例阻尼結構設計的雙反應譜方法；對于耗能器的數量和位置優化進行了一些探討和研究。 -
One dimensional equation can be obtained through extending the stream function and forcing term into fourier series, and this equation can be solved by assuming the traveling - wave solution. besides converting the topographies to flat bottom, the transforms also change the distribution of forcing. for subcritical topography, the intensity of
所用的求解方法為將解和強迫項在變換平面內進行付里葉級數展開，得到一維的波動方程，通過設行波解的方法求解該一維波動方程，所有模態解的疊加即為內潮生成問題的解。
