The use of steel and concrete in skyscraper construction has been a major advancement, allowing for taller, more rigid structures with extended lifespans. Steel offers greater stiffness and provides resistance against strong winds while its lightweight design allows for efficient use of land.
13 de may. de 2021 · Skyscrapers of the ’20s and ’30s were framed with steel columns, beams and girders fitted together by four-man riveting gangs.
Innovations in steel production were integral to the era of the skyscraper. In 1897, Henry Grey revamped the rolling process to include wide-flange sections, enabling designers to create taller, more efficient structures. Improvements continue to influence the skyscraper city and its revival.
Vertical supports can come in several types, among which the most common for skyscrapers can be categorized as steel frames, concrete cores, tube within tube design, and shear walls. The wind loading on a skyscraper should also be considered.
The central support structure of a skyscraper is its steel skeleton. Metal beams are riveted end to end to form vertical columns. At each floor level, these vertical columns are connected to horizontal girder beams.
Introduction Steel and the skyscraper have a partnership that spans more than a century (see Figure 1). In combination with various advances in building technologies, steel enabled the 1930s surge in high-rise construction and high-strength steel led to its 1970s renaissance.
The weight and fortitude of steel makes it the perfect choice for skyscrapers and other large infrastructure projects; its malleability allows for versatile design and, ultimately, timeless architecture. Put simply, steel remains the go-to material for structural integrity.
