Then a simplified computational modal of damping isolation systems is established for a platform structure, and the relationships between the parameters of isolation layer and structural damping ratio, including their vibration - suppressed effect on the whole structure and the relative displacement of isolation layer are studied, and the simulation analysis under several representative load case of random wave force and earthquake affairs is performed. under random wave force, using complex mode theories, non - classically damp problems considering the interaction between the structure and wave, lying in deepwater, are studied. and the resolution solution of structural response are achieved. the results of calculating and analysing show that adding damping isolation to a jacket is an effective way to reduce vibration for offshore platforms

Earthquake and wind ), because of the damping matrixes of the two structures " motion equations are both non - classical, the dynamic equation ca n ' t be decoupled by the traditional real - mode analysis ( the mode - superposition method ). though, in this thesis the complex - mode analysis is used to solve the stationary and non - stationary random earthquake response of structures and their analytic expressions are got. on the basis of these expressions, the optimal parameters of the two structures " isolation & seismic decrease equipment are analyzed
目前，基礎隔震結構、 「加層減震」 （ tmd減震）結構正逐步應用於工程實際，由於這兩種結構在動力荷載（如地震、風）作用下動力方程中的阻尼矩陣為非經典情形，傳統的實模態分析方法（振型分解法）不能使動力方程解耦，因此本文運用復模態分析方法求得了結構在平穩和非平穩隨機地震激勵下結構隨機地震響應的解析表達式，在此基礎上進行了基礎隔震和tmd減震裝置參數的優化分析。 -
