Question

Which of the following tall building(s) is/are having bundled-tube structural system?

• A. Sears Tower, Chicago
• B. The 42, Kolkata
• C. O-16 Building, Dubai
• D. Bank of China, Hong Kong

Hint:

The bundled-tube system is commonly used in very tall buildings because it provides enhanced stability and resistance to wind forces.

Answer 1

The Correct Option is A

The bundled-tube structural system is a design used in tall buildings where multiple tubes are bundled together to form a rigid structure. This system helps in distributing the load more efficiently and allows for taller buildings. Let’s analyze the options:

Sears Tower (now Willis Tower), Chicago: This is one of the most famous buildings with a bundled-tube system. The tower consists of nine interconnected tubes, which provide stability and allow it to reach a height of 1,450 feet. Hence, (A) is correct.

The 42, Kolkata: The 42 in Kolkata is a modern skyscraper, but it does not use the bundled-tube system. It uses a conventional core-and-outrigger system. Thus, (B) is incorrect.

O-16 Building, Dubai: The O-16 Building in Dubai does not use the bundled-tube structural system either. It is more of a regular core-and-frame structure. Thus, (C) is incorrect.

Bank of China, Hong Kong: The Bank of China Tower in Hong Kong features a bundled-tube system, with the four tubes supporting the building's structure and providing stability. Hence, (D) is correct.

Conclusion: The correct options are (A) Sears Tower, Chicago and (D) Bank of China, Hong Kong, as these buildings use the bundled-tube structural system.
