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

A bundled-tube structural system in tall buildings combines multiple tubes to form a rigid structure, enabling efficient load distribution and greater heights. Let's examine the options:

Sears Tower (now Willis Tower), Chicago: This iconic building exemplifies the bundled-tube system, employing nine interconnected tubes for stability and a height of 1,450 feet. Therefore, (A) is valid.

The 42, Kolkata: While a modern skyscraper, The 42 does not utilize a bundled-tube system; it employs a conventional core-and-outrigger system. Consequently, (B) is invalid.

O-16 Building, Dubai: The O-16 Building in Dubai does not feature a bundled-tube structural system, opting instead for a standard core-and-frame construction. Thus, (C) is invalid.

Bank of China, Hong Kong: The Bank of China Tower in Hong Kong incorporates a bundled-tube system, with four tubes providing structural support and stability. Accordingly, (D) is valid.

Conclusion: Options (A) Sears Tower, Chicago and (D) Bank of China, Hong Kong correctly identify buildings that utilize the bundled-tube structural system.
