On August 3, the demolition of the roof mast of the SEG Plaza Building in Huaqiangbei, Shenzhen is underway.
A few days ago, the cause of the shaking of the SEG Plaza Building in Huaqiangbei, Shenzhen has been identified. Through technical investigations, environmental and equipment operation investigations and tests, the expert team ruled out influencing factors such as subway operation, surrounding engineering construction or blasting, and air-conditioning unit operation. , Through the key analysis of wind-induced vibration and structural cumulative damage.
The expert group believes that the coupling of wind-induced vortex-induced resonance of the mast and changes in the dynamic characteristics of the building and the mast has caused the SEG Building’s perceptual vibration. Therefore, it was decided to demolish the roof mast. After being demolished, it will be re-arranged on the roof of the building.
