What does the term "steel-frame construction" refer to in architecture?

The term "steel-frame construction" refers to a technique that allows for skyscraper designs due to its use of a skeletal framework composed of steel. This method provides significant structural support and enables architects to create taller and more complex buildings than would be possible with traditional materials like wood or masonry. The rigidity and strength of steel allow for larger open spaces within the building, which is crucial for modern architecture, particularly in urban environments where maximizing usable space is key.

This construction approach revolutionized the skyline of cities, facilitating the vertical growth of structures and leading to the iconic silhouette seen in many metropolitan areas today. The use of steel frames makes it possible to support heavy loads while managing lateral forces, such as wind and seismic activity, which is essential for the stability of high-rise buildings.
