The Shanghai World Financial Center was planned to be the tallest building in the world when it was designed in 1997. The 97 Story building would surpass the spires of the Petronas Towers in Malaysia. When Construction was restarted in 2003, the 508 Meter Taipei 101 in Taiwan was already underway to becoming the World's Tallest Building. Plans where changed but the Tower couldn’t be built any higher than its present height at 492 meters since the already done foundation was meant to support a 460 meter tall building.
The structure features 3 floors of underground parking, shops and a conference center on floors 1 through 5, offices on floors 7 through 77, a hotel located on floors 79 through 93, and finally observation and exhibition areas on floors 94 through 100.
To protect the building from fierce winds, the Shanghai World Financial Center holds two tuned mass dampers below its observation floors to reduce the building’s sway during windstorms and earthquakes.More
