About Trump Tower
Trump Tower is a 58-story skyscraper in New York City located at 721 Fifth Avenue, at the corner of East 56th Street. The mixed-use tower was developed by Donald Trump and the Equitable Life Assurance Company. Designed by Der Scutt of Swanke, Hayden Connell, it was completed on the 30th of November 1983. The tower is a reinforced concrete, shear-wall/core structure and was the tallest structure of this type in New York City when completed. A concrete hat-truss at the top of the building ties exterior columns with the concrete core. This increases the effective dimensions of the core to that of the building in order to resist the overturning of lateral forces (wind, minor earthquakes, and impacts perpendicular to the building’s height). A similar structure was used for Trump World Tower. Ordinarily a building of that height could not have been built on the small site.
