SEG Plaza

SEG Plaza is a engineering topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand SEG Plaza rather than just read about it. In short: SEG Plaza (Chinese: 赛格广场) is a skyscraper in Shenzhen, Guangdong Province, China. Completed in 2000 and located at the junction of Shennan Road and Huaqiangbei Electronics Market, it originally stood 356 metres (1,168 ft) tall including the height of the original antenna which has since been removed.

Key takeaways

SEG Plaza belongs to engineering; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect SEG Plaza to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of SEG Plaza from memory before moving on to harder problems.

Reference excerpt

SEG Plaza (Chinese: 赛格广场) is a skyscraper in Shenzhen, Guangdong Province, China. Completed in 2000 and located at the junction of Shennan Road and Huaqiangbei 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 the 21st tallest in China and the 72nd tallest in the world. The observation floor at the 69th level used to offer views over Shenzhen and northern Hong Kong but has been converted to office space. It is the home of, and named after the Shenzhen Electronics Group (SEG). It can be reached by Huaqiang North Station and Huaqiang Road Station of the Shenzhen Metro.

History

Construction The tower comprises a steel-reinforced concrete core with external steel tube columns filled with concrete. It has four basement levels. 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).

2021 shaking On 18 May 2021, the building began to shake, leading to an emergency evacuation. The building remained closed three days later while inspections were carried out. 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. 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. The building's exact new height is uncertain, the original mast having accounted for approximately 210 feet (64 m) of it.

Floors The roof height of the building is 292 metres (958 ft). There are a total of 71 stories above ground (72 when counting the helipad) and 4 stories underground. The total floor space is 170,000 square meters. The four stories underground are parking levels.

SEG Electronics Market and the main building The floors from the 1st floor through to the 10th floor are taken up by the SEG Electronics Market, a major market of electronics components and finished products of international importance. The names SEG Electronics Market and SEG Market are also sometimes metonymically used for the surrounding area, including other electronics markets in nearby buildings. The 11th floor is a refuge floor. Floor M and 12th floors are European restaurants and a food supply center for the administration. Floors 13 through 69 are white-collar worker office floors (of which floors 19, 34, 49 and 63 are emergency equipment cabinet and shelter levels); the 70th and 71st floors are observation decks (Closed) and the 72nd floor is a helicopter landing pad. SEG Plaza's elevators are made by OTIS which can travel to 6 metres per second (1,200 ft/min).

Worked examples

Example 1 — a first encounter with SEG Plaza

Start with the simplest possible case. Write down what SEG Plaza claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In engineering, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to SEG Plaza before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about SEG Plaza ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of SEG Plaza

In research: SEG Plaza appears in engineering research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses SEG Plaza in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: SEG Plaza is common in secondary-school and first-year university syllabi. It links to neighbouring topics 2000 establishments in Shenzhen, Buildings and structures completed in 2000, Hotels in Shenzhen, so understanding it makes those chapters shorter.
In everyday life: Look for SEG Plaza outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Frequently asked questions

What is SEG Plaza in simple terms?

Why does SEG Plaza matter?

Because it connects several engineering ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.
