海上平台利用TLD的减震研究
|
摘要
通过减震试验和数值计算来研究液体调频阻尼器(TLD)在地震荷载作用下对渤海CB32A海上平台的减震作用。减震试验主要研究缩尺后TLD对平台模型在EL Centro波、天津波及规范谱拟合人工波作用下所产生的振动反应的影响。数值计算主要研究原型结构受上述地震波的激励作用的TLD减震效果。结合试验和理论分析结果,给出了海洋平台结构的TLD减震控制的一般设计方法,以供设计人员参考。
The model tests and numerical analysis were performed in order to study the vibration-absorbing of CB32A offshore platform subjected to the earthquake by means of the tuned liquid damper.The vibration-absorbing tests researched the responses of the model platform with TLD acted by El-Centro seismic wave,Tianjin seismic wave and the artificial seismic wave based on response spectrum from National Code.The numerical analysis focused on the vibration absorption effect of TLD for the prototype platform.Meanwhile,the procedures to design the vibration-absorbing control with TLD on the offshore platform were proposed on the base of experiment and computation under earthquake.
