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。
