深圳赛格大厦振动事件有了结论,但还有这5大疑问-新闻中心-南海网
深圳赛格广场大厦这次的振动之所以能够明显地被人们感觉到,是因为振动的幅度达到了一定的程度,也就是产生了共振现象。新京报记者查阅资料发现,当外力的频率和结构自身振动的频率相同时,会产生共振现象。 郑涛介绍,共振现象在日常生活中也有应用,比如我们会尽量避免在过桥时齐步走,这样会使得桥梁振动的幅度逐渐加大,超过一定程度,就会出现桥梁坍塌。另一方面,划龙舟和拔河时,我们也会利用大家协调一致同步用力产生共振,从而产生最大的作用力。 在此次深圳赛格广场大厦振动事件中,专家通过调查得出结论:在稳态且持续一定时间的特定风场条件下,大厦桅杆产生了频率为2.12赫兹的第四阶反向位非对称涡激共振,激发了大厦主体结构频率同为2.12赫兹的高阶弯扭组合模态,进而引起大厦主体结构有感
