Amazon Quiz (August 31, 2021): Which are the tallest towers of this kind in the world?
1) Emirates Towers
2) City of Capitals
3) Petronas Towers
4) Palm Towers
Answer: Petronas Towers
The Petronas Towers are a set of two almost identical structures located in Malaysia's national capital Kuala Lumpur. Even though the towers continue to remain the tallest twin towers in the world, the designation of being the tallest structure was lost in 2004.
The 88-floor towers are constructed largely of reinforced concrete, with a steel and glass facade designed to resemble motifs found in Islamic art, a reflection of Malaysia's Muslim religion. Another Islamic influence on the design is that the cross-section of the towers is based on a Rub el Hizb, albeit with circular sectors added to meet office space requirements. The circular sector is similar to the bottom part of the Qutub Minar.
The towers were designed by Argentine architect César Pelli. A distinctive postmodern style was chosen to create a 21st-century icon for Kuala Lumpur, Malaysia.
Planning on the Petronas Towers started on 1 January 1992 and included rigorous tests and simulations of wind and structural loads on the design.
Seven years of construction followed at the former site of the original Selangor Turf Club, beginning on 1 March 1993 with excavation, which involved moving 500 truckloads of earth every night to dig down 30 metres (98 ft) below the surface.
