What is an essential feature of the structural frame of a skyscraper?

1. It acts solely as a decorative element

2. It carries the weight of the curtain wall

3. It withstands the dead load of the building

4. It enhances the building's energy efficiency

The correct answer is: It withstands the dead load of the building

The structural frame of a skyscraper is primarily designed to support the entire weight of the building, which includes all its components and their loads, known as the dead load. The dead load comprises the materials that make up the structure itself, such as concrete, steel, and finishes. This framework is crucial for maintaining the stability and integrity of the building, allowing it to safely transmit these loads down to the foundation and into the ground. While it is true that other elements, such as the curtain wall, do play a role in the overall design and efficiency of a skyscraper, the structural frame’s main responsibility lies in providing robust support for the building's weight. This feature ensures that the skyscraper can withstand various forces, such as wind loads and seismic activity, making it a fundamental aspect of the design and engineering of tall buildings. Therefore, recognizing the importance of the structural frame in supporting the dead load is essential for understanding skyscraper stability and design principles.
