More significantly, this period was also marked by the development of a new structural system in which a load-bearing exterior structure acts as a rigid tubular cantilever, the most efficient solution for resisting wind loads on buildings over 70 storeys. It was first applied to reinforced-concrete structures from about 1963, but the development of the braced tubular cantilever in steel (by Myron Goldsmith and Fazlur Khan) made possible the most spectacular skyscrapers of the 1970s [including] the twin 110-storey tube towers of New York's World Trade Center (1964-1974, destroyed 2001) by Minoru Yamasaki and Emery Roth & Sons, clad in stainless steel with gothicized detailing at base and top.
