Humanity has become obsessed with breaking its limits, creating new records only to break them again and again. In fact, our cities’ skylines have always been defined by those in power during every period in history.
In many ways, the race to the sky, the need to build taller, is as old as time. Yet it’s over the past century that we’ve seen a significant leap in the total height of our tallest skyscrapers (by define, a skyscraper is a building that exceeds 330 feet).
The majority of industrial building superstructures are framed in structural steel, although a small percentage are in precast concrete. Steel is used primarily for its large strength-to-weight ratio, enabling it to span large distances economically.
