最近几天,深圳赛格大厦晃动事件引发公众关注。

The 356-meter-tall SEG Plaza in Shenzhen first began shaking on Tuesday afternoon. All those inside were evacuated within 90 minutes, local authorities said.
5 月 18 日下午,356 米高的深圳赛格大厦第一次发生晃动。当地政府表示,楼内所有人员在 90 分钟内全部疏散撤离。

监测数据未显示异常情况

From 9 pm on Tuesday to 3 pm on Wednesday, a number of professional organizations closely monitored the skyscraper's vibration, tilt and subsidence. The three indicators were far below levels that would prompt concerns, and data from the monitoring did not reveal any abnormalities, the city's housing and urban-rural development bureau said in a statement.
5 月 18 日晚上 21 时至 19 日下午 15 时,多家专业机构对赛格大厦的振动、倾斜、沉降等情况进行实时监测。深圳市住建局表示,该三项指标均远远小于规范允许值,监测数据未显示异常情况。

A preliminary investigation had found the wobbling was vertical rather than horizontal and that it was caused by a combination of winds, two underground rail lines under the building and the stretch of the steel caused by the rising temperature.
初步调查结果显示,深圳赛格大厦系上下震颤而不是左右摆动,造成震颤的原因是多种因素耦合,包括风的影响,两条地铁从楼下经过以及近期气温升高对钢结构产生的影响。

5 月 21 日,一份落款为深圳赛格集团有限公司的通知显示:为确保赛格大厦检测工作顺利进行,不受外界干扰,经赛格集团研究决定,自 5 月 21 日零时起,暂停所有业主、商户、租户进出赛格大厦写字楼和电子市场(all business owners, vendors and tenants will be denied access to the plaza),待相关检测工作完成后再有序开放,有关事宜另行通知。

深圳市将根据楼体结构排查情况,研判大厦恢复开放时间。鉴于该大厦未安装阻尼器(tuned mass damper),专家建议,下一步可以考虑安装阻尼器以提高防风防震能力和舒适度。
