［摘要］銀泰中心主塔樓為北京CBD標(biāo)志性建筑之一，樓高249.9m，共62層，為超高層鋼結(jié)構(gòu)，是我國(guó)首次在新建超高層鋼結(jié)構(gòu)建筑中采用消能減震措施。闡述了結(jié)構(gòu)耗能減振的研究及發(fā)展現(xiàn)狀，給出了北京銀泰中心主塔樓的結(jié)構(gòu)方案設(shè)計(jì)的特點(diǎn)，然后對(duì)線性及非線性液體粘滯阻尼器的工作原理及特點(diǎn)進(jìn)行對(duì)比，并介紹了主塔樓阻尼器的樓層布置及所采用的支撐類型。通過(guò)計(jì)算表明在設(shè)置非線性粘滯阻尼器后，銀泰中心主塔樓的風(fēng)振加速度降低，主塔樓的抗震性能同時(shí)得到了改善。通過(guò)能量原理得到了工程設(shè)置粘滯阻尼器后的附加阻尼比。最后對(duì)阻尼器的測(cè)試情況作了介紹，測(cè)試結(jié)果表明銀泰中心用阻尼器的性能達(dá)到設(shè)計(jì)要求。

Abstract:The Silvertie Hotel is one of the dominant super high-rise structures in the Central Business District of Beijing. The 62 stories building 249.9 meters height is the first in China to adopt the energy dissipation technology. This article briefly introduces the research and the development of the liquid viscous dampers by way of describing the structural characters of the Silvertie building, explaining the working principles of the linear and non-linear liquid viscous damper, then recommends the layout of the dampers as well as gives the damper connection configuration adopted in this building. The damping technology can successfully reduce the acceleration caused by the wind vibration, greatly improve aseismatic performance. The paper gives an additional damping ratio of the project with viscous dampers using energy principle. Finally the process of the damper testing is introduced, the testing results indicate that the dampers dynamic performance has reached the standard of the design.
Keywords:nonlinear; viscous damper; energy principle; testing
