SEG Plaza (Chinese:赛格广场) is askyscraper inShenzhen,Guangdong Province,China. Completed in 2000 and located at the junction ofShennan Road andHuaqiangbei Electronics Market, it originally stood 356 metres (1,168 ft) tall including the height of the original antenna which has since been removed. It was the21st tallest in China and the72nd tallest in the world.[1] The observation floor at the 69th level used to offer views over Shenzhen and northernHong Kong but has been converted to office space. It is the home of, and named after theShenzhen Electronics Group (SEG). It can be reached byHuaqiang North Station andHuaqiang Road Station of theShenzhen Metro.
The tower comprises a steel-reinforced concrete core with external steel tube columns filled with concrete. It has four basement levels.[4]
It was constructed for Seg Plaza Investment and Development with investment from the Shenzhen SEG Group Co. Ltd. The tower was designed by Chinese architecture firm Hua Yi Designing Consultants Limited (Chinese:华艺设计顾问有限公司).[5]
On 18 May 2021, the building began to shake, leading to an emergency evacuation.[6][7]
The building remained closed three days later while inspections were carried out.[8] An initial investigation ruled out an earthquake as the cause of shaking, with the main structure of the building safe without any cracks found at the building or the surroundings.[9]
Authorities later declared the shaking as a result of winds which caused a rooftop mast to vibrate. The mast was used for guiding aircraft and lightning protection. The mast has since been removed and replaced by an alternative structure providing the same functions.[10] The building's exact new height is uncertain, the original mast having accounted for approximately 210 feet (64 m) of it.
The roof height of the building is 292 metres (958 ft). There are a total of 71 stories above ground (72 when counting thehelipad) and 4 stories underground. The total floor space is 170,000 square meters. The four stories underground are parking levels.
The floors from the 1st floor through to the 10th floor are taken up by theSEG Electronics Market, a major market of electronics components and finished products of international importance.[11][12][13][14] The namesSEG Electronics Market andSEG Market are also sometimesmetonymically used for the surrounding area, including other electronics markets in nearby buildings.
The 11th floor is arefuge floor. Floor M and 12th floors are European restaurants and a food supply center for the administration. Floors 13 through 69 arewhite-collar worker office floors (of which floors 19, 34, 49 and 63 are emergency equipment cabinet and shelter levels); the 70th and 71st floors areobservation decks (Closed) and the 72nd floor is ahelicopter landing pad.
