摘要

Engineers designing a Manhattan skyscraper with offices in the lower floors and residences in the upper found that they had to employ several unusual methods to accommodate client needs. In addition to relocating columns and transferring loads through outrigger systems, they added a uniquely designed tuned-mass damper to counteract wind motions. It is said that Cass Gilbert—the 19th-century architect who designed New York City's Woolworth Building, the U.S. Supreme Court Building, in Wash-ington, D.C., and numerous other significant structures—once noted that skyscrapers are "machines that make the land pay." Engineers prefer to think of tall buildings in terms of elegant solutions, optimized frames, and structur- al expression, but when it comes to commercial construction, making the land pay can indeed become a key criterion. The tower that will soon be completed in the New York City borough of Manhattan at 731 Lexington Avenue is a prime example of engineering in service to the bottom line. Indeed, the greatest challenges arose from real estate considerations.
