The development of the steel-framed structure was the technological breakthrough that made it possible to build skyscrapers. Before the late 19th century, buildings were limited in height by the strength of their load-bearing walls. Steel frames, however, can support much greater weight, allowing buildings to be built much taller.
The first steel-framed skyscraper was the Home Insurance Building in Chicago, completed in 1885. This building was 10 stories tall, and its steel frame allowed it to withstand the strong winds that are common in Chicago. The success of the Home Insurance Building led to the construction of many other steel-framed skyscrapers in Chicago and other cities.
Steel-framed structures have a number of advantages over load-bearing walls. They are much lighter, which reduces the weight of the building and makes it less likely to collapse in an earthquake. They are also more flexible, which allows them to sway in the wind without collapsing. Steel-framed structures are also fire-resistant, which makes them less likely to be destroyed in a fire.
