      深圳赛格广场大厦晃动可能的原因及结构体系

      赛格大厦晃动

       5月18 日，有网友爆料，深圳华强北赛格大楼发生晃动，大厦有轻微的倾斜和晃动，现场有人员从大厦撤离，周边市民聚集围观，具体原因还不明。

      02

      结构体系

      深圳赛格广场位于深圳市交通干道深南中路与华强北路交汇处，由深圳赛格集团投资兴建，是目前世界最高的钢管混凝土结构大厦，是深圳市跨世纪的标志性建筑。总高345.8米，总建筑层79层，地上 75层，地下4层，总建筑面积达17万平方米。

      结构采用钢管混凝土结构，塔楼为框筒结构,外框由钢管混凝土柱和钢梁组成，内筒为钢管混凝土密排柱和实腹钢裙梁组成。筒内在两个主轴方向各设4道劲性混凝土剪力墙。裙房和地下室为12 m柱网的钢管混凝土柱与型钢混凝土梁组成的框架及剪力墙结构。


      从裙房顶开始每隔15层设置一道加强层，在加强层内、核心筒与外框柱之间设置了16榀钢桁架,并在该层的外框柱周边又设置了周边钢桁架。

      原因分析

      超高层设计中减少位移的两个关键点是：一是减少荷载，二是增加刚度。


      减小荷载：选择风荷载体型系数小的形体，减少风荷载；用质轻高强的材料，减少质量从而减少地震作用。


      增加刚度：增加抗侧力构件的刚度，如设置加强层等等。


      因此深圳赛格大厦出现位移异常，大幅晃动的原因无非是异常荷载作用或者本身抗侧力构件刚度的突变。


      一：荷载作用


      荷载作用方面有：风荷载，水平地震作用，地基不均匀沉降，列车风作用（下有地铁），温度作用。


      1、风荷载：深圳当天无大风，发生晃动时瞬时风速为5级，在允许范围内无异常，因此可排除由于大风作用引起的共振现象。


      2、水平地震作用：当天无地震，因此可排除地震引起。


      3、地基不均匀沉降：经核查，周边未见地面开裂，因此可排除地基不均匀沉降引起。


      4、列车风：该大厦下有地铁通过，列车通过及制动、启动会对所通过的结构产生动力冲击作用，使结构发生振动。但地铁在地下，列车风作用对地上结构直接产生较大侧移的可能性不大。


      5、温度作用：温度作用直接引起整个结构的晃动的可能性不大。


      二、结构抗侧刚度突变：


      随着荷载的不断作用，材料的老化，反复的温度作用，高应力状态的节点或者构件有可能出现破坏。如加强层桁架节点，有可能在高应力状态下忽然破坏，高应力释放引起振动而产生整体结构的晃动。


      综上所述，最可能的原因就是结构抗侧刚度突破，如检查抗侧力构件、节点及者加强层桁架等是否有破坏。


      以上仅为作者根据结构概念推断，实际原因根据专家实地调查及检测后公布。

      只看楼主 我来说两句
      • 天柱
        天柱 沙发

        趁机测下结构阻尼比，是不是规范定的4%太大了？估计大约是2.5%。
