DESIGN APPLICATION OF HIGH STRENGTH STEEL IN GREENLAND CENTRAL PLAZA IN ZHENGZHOU

To promote more rapid development and application of high strength steel in China，the material was applied in Greenland Central Plaza in Zhengzhou． The material strength and design parameters were studied，and the buildings structural key indexes before and after the application of the high strength steel are analyzed． The study shows that when the high strength steel is applied in a high-rise building 20% steel can be saved without any influence to the structure response． The application of high strength steel in civil buildings should be promoted．
