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
針對某一典型平臺結構，建立了海洋平臺結構阻尼隔振體系簡化計算模型，進行了波浪荷載工況和地震工況的數值模擬，研究了隔振參數與結構阻尼比的關系以及它們對結構整體和隔振層層間相對位移的控制效果，運用復模態理論研究了位於較深水位的固定式導管架海洋平臺在隨機波浪力作用下考慮結構與波浪相互作用時運動方程中非經典阻尼的解耦問題，獲得了結構響應的解析解。Currently, researchers from home and abroad usually use simplified models in the aseismatic analyses of immersed tunnels, which can not properly simulate the two functions of the soil, while the finite element method solves this problem successfully, and the development of numeric calculation and computer technology lays a solid basis for its application, it is a pity that the applications of fem is not common currently
目前，國內外對沉管隧道進行抗震分析時，大多採用簡化計算模型，將土的作用以等價彈簧和阻尼器代替，不能適當模擬土既是地震波的傳播介質又是結構物的支承介質的雙重作用。動力有限元法的連續介質模型很好的解決了這一問題，數值計算理論和計算機技術的發展為該方法的應用奠定了堅實的基礎，然而，目前這方面的應用還很少。In the area of elasto - plastic dynamic analysis of frame with friction energy dissipation, the design - oriented nonlinear seismic response time history analysis method for frame with friction energy dissipation has been set up. and the corresponding program idaff is developed using visual c + + language ; the analytic solution of a single - damped - story braced frame with friction energy dissipation under the sine wave excitation has been give ; besides these, a vibration reduction analysis of multi - story frame with friction energy dissipation has been given in the paper and some useful conclusions have been drawn
在摩擦耗能框架結構彈塑性動力分析方面，本文建立了面向設計的摩擦耗能框架結構非線性地震反應時程分析方法，並利用vc + +編制了相應的程序idaff ；給出了帶有摩擦耗能器的有阻尼單層框架在正弦波激勵下反應的解析解；同時本文從多自山度的角度出發對摩擦耗能框架的影響因素進行分析，得出相關的結論。
