Structural Design Fused with Cultural Heritage
Rising 452 meters above Kuala Lumpur, Petronas Twin Towers are identical 88-story buildings – the tallest twin towers in the world - which culminate in stainless steel pinnacles. The dramatic Islamic-themed towers feature a sky bridge at floors 41 and 42 that connects the towers and creates a visual gateway to a major public park. The towers were the tallest buildings in the world from 1998 to 2004.
- We engineered the sky bridge with slender structural members rather than heavy trusses to be compatible with the building’s architecture.
- The preassembled bridge was lifted into place and joined to each tower more than 150 meters above street level.
- A pair of steel tubes support the 58-meter sky bridge. The tubes connect to rotating bearings on the 29th floor of each building to allow for independent tower movements caused by wind loads.
- The complex also includes a seven-story retail facility, an acoustically isolated 864-seat concert hall and a 5,143-car underground garage. We provided structural design for these components.
- The towers were the tallest buildings in the world until 2004 when it was surpassed by Taipei 101 in Taiwan. Thornton Tomasetti also provided structural design for that supertall tower.
