Analysis of the Causes of Abnormal Vibration of Shenzhen SEG Building

The abnormal shaking of Shenzhen SEG Building occurred from May 18th to 20th, 2021. Probable sources which might cause the vibration and possible environmental disadvantages of SEG Building were analyzed and sorted out. Firstly, distance of the source was distinguished based on the directions and patterns of vibration, as well as features of group vibration or single vibration. Then the possible causes were determined based on the dynamics and statics relations between SEG buildings and the most frequently adverse environmental factors and their long-term impact. We suggest focus on whether fatigue damage is caused by wind load and ground vibration in the building structure and whether the foundation is weakened by soil erosion. The methods and approaches to inspect influence factors are given in detail.
