The Petronas Towers





The skybridge
The interior of the skybridge

The Petronas Towers, located in Kuala Lumpur, Malaysia, are very interesting. Since their completion in 1998 for the Petronas Oil Company, they have held many records, and still hold some of them, with their height of 1,483 ft. For example, they still are the tallest twin towers in the world, and one of the towers by itself was the tallest building in the world. It was also the first building outside America to break the record of tallest building in the world. The towers each have 88 floors, and are connected by a two-story skybridge at the 41st and 42nd stories. The skybridge really helps to connect the two towers, symbolising a doorway or a gateway into the city. The skybridge is not really attached permanently to the towers, because at times the towers sway multiple feet in the wind, which would result in a cracked skybridge. Instead, when the buildings sway, it slides back and forth inside them. It also gives the towers some amount of stability when they are being blown by the wind. The tower is based on the shape of an 8 point star, with many elaborations added:


 While the towers are very tall, in my mind, they have a lot of horizontal emphasis. The towers have a distinct ribbed look, not a curtain of glass. This is because each window has a sunshade above it, and these are continuous along the top of the windows of each level. This is one of the reasons that the two towers have a horizontal emphasis. Another is the skybridge, which gives the two towers a bond, which is strictly horizontal. The towers are supported by extremely strong reinforced concrete. So strong, that there is no need to have a tuned mass damper in either of the towers. 


All in all, these twin towers are amazing buildings.
