Petronas Twin Towers

Petronas Twin Towers hitting the skies of Kuala Lumpur at 451.9metres from street level, the American structure has lost its long-standing glitter to Malaysia.

From all counts, the Petronas Twin Towers is a modern-day architectural marvel, with the stupendous design undertaken by world-renowned architects Cesar-Pelli & Associates, selected through an international competition in 1991. The floor plate of the Towers took into perspective geometric patterns common in Islamic architectural heritage. The geometric shape facilities efficient office layout planning while the contiguous windows provide occupants with panoramic views of the city and surrounding areas.

The exterior of the Petronas Twin Towers is organized in horizontal ribbons of vision glass and stainless steel which glint and shimmer spectacularly in the sun. The structures of the Tower consist of a core and cylindrical tube frame system constructed entirely of cast-in situ high strength concrete. Core walls (23 metres by 23 metres) from the inner core while a circular cylindrical tube of 46-metre diameter forms the outer tube.

Floor framing at Tower levels are concrete fill of conventional strength on steel floor decking supported by steel beams. The average office storey height is 4 metres with floor to ceiling height of 2.65 metres. The imposing 73.5-metres tall pinnacles, visible from practically all parts of the city, are the crowning glory of the Twin structures.

Linking the Twin Towers at the 41st and 42nd levels is the 58.4-metre Skybridge standing 170 metres above street level. Its arch supports form a symbolic gateway to the city.
