Zhongyuan Tower, also known as Henan Radio and Television Tower or "Tower of Fortune", is located in Zhengzhou, China.[1] It is a multi-functional commercial, artistic and cultural center integrating radio and television broadcasting, tourism, cross-border trade, cultural performance, catering and leisure.[5] The tower measures 268 metres (879 ft) high and the top antenna is 120 metres (390 ft) high, with a total height of 388 m.[6] It is the world's second tallest steel tower after the Tokyo Skytree.[citation needed]
Design
It required 22,000 tons of steel; its heaviest component is 40.2 tons. The structure is hot-dip galvanized and treated with fluorocarbon paint. It uses 850,000 high-strength bolt connections, replacing high-altitude welding technology. The installation accuracy is 99.98%[clarification needed].[7]
The outer surface is a hyperbolic parabola. From the air, it looks like a plum blossom with five petals. The plum blossom is the provincial flower of Henan province. Five petals are homophonic with "five blessings" in Chinese. Looking up from the ground, the tower is like a static firework that spins upward and flies gracefully. The shape of the tower base is like a tripod, which was a symbol of power and prestige in ancient China. The shape of the tower is like the ancient Chinese musical instrument Chime Bells, which symbolizes the tower's communication function.
Structure and function
