非线性TMD对超高层结构减震效果影响分析

Earthquake resistance effect analysis of super high-rise structure with non-linear TMD

当前的减震技术主要集中应用在基础隔振和消能减震体系中,有较好效果但使用条件也受限制。结合橡胶支座基础隔震和调谐质量阻尼器的研究成果,提出了在超高层结构中应用非线性"调谐质量阻尼器"的减震技术。同时利用有限元软件分析了不同地震作用下采用了非线性"TMD"减震技术和不采用减震技术的某高层结构的地震反应,发现了非线性TMD技术对超高层建筑具有明显的减震效果。该技术对超高层结构的减震具有参考价值。

Now damping-isolation technology is mainly used in the base isolation and energy dissipation system.It is very useful,but the range of applications is restricted.It shows non-linear TMD damping-isolation technology in the super high-rise structure on the basis of research results of rubber bearing and tuned mass damper.By analysing high-rise structure seismic response with non-linear TMD technology by finite element software in the different earthquake,it has been found that non-linear TMD has obvious damping effects on super high-rise structure in contrast with primitive structure.Non-linear TMD technology has great reference value in high-rise structure damping.
