Citicorp Center in New York (USA) - skyscraper with slanted roof

Standing between the high-rise skyscrapers with flat roofs in the city center, Citicorp with its sloping roof has become a symbol of corporate identity in this area. The sloping roof gives expression to the high modernity of the building.

Citicorp Center was the first skyscraper in the United States containing a mechanism to counteract the effects of swaying and trembling under the influence of wind and earthquakes.

In 1978, chief engineer William LeMessurier discovered a building defect, said the skyscraper was too weak to resist wind blowing at 70 miles per hour. Over the next three months, the team welded two-inch plates to each of the 200 slits. By solving this problem.

A 30-page acronym describing construction errors and mistakes in the Citicorp building has been published, it is called "SERENE project".

The building is distinguished not only by the roof but also by its 7-story atrium overlooking the street, designed for shops and restaurants.

The slope at the apex is 45? and almost 50 meters.

Double-deck elevators reduced the area needed for vertical movement, thus leaving more space for renting offices.

The computer controls humidity throughout the building and ensures the stability of the entire structure.

Profitability of the building: 1.1 million.
