【Abstract】 In this paper,it’s demonstrated firstly that the three core values of steel structures,i.e.,the lightest structure,the shortest construction period and the best ductility.Then the classification and innovation is set forth,and finally the comparison of structural efficiency of large-scale steel structures at home and abroad is also carried out.The key of the design of steel structures is to select structural scheme correctly.The research results show that otherwise,optimization is useless.更多还原
