摘要
还没有全部完工开放就遭遇2003年强烈地震考验的57层225m高的高层钢结构——墨西哥TorreMay-or大楼,经受了此次地震的考验。作为世界上首批采用阻尼器抗震的高层建筑,采用了全新的设计理念、先进的优化、构造和安装技术、成功的抗震手段,其设计理念和计算方法都为世界地震工程界开创了一个值得学习的先例。最后提出了一点看法,希望引起进一步讨论。
The Torre Mayor building used seismic damper to do seismic protection firstly which was subject to the severe earthquake in 2003.Not only set up a totally new idea,an optimal configuration and installation,but also result perfect effect of reducing vibration,its design idea and method provided reference to earthquake engineering field.At last,a suggestion was put forward.
