近年来,随着建筑钢结构的发展,为求保证建筑的安全性、经济性以及对于空间的充分利用以及建筑外观的造型要求,建筑业对于新型钢结构的性能需求也变得多样化。钢铁产业为此投入了大量的人力物力,用于研发高性能结构用钢,并为这类钢材附加了很多规格外的性能保障。反观国外发达地区与国家,建筑业将会是钢材使用的重要市场之一,为更好的服务建筑市场,推动建筑行业的技术升级,钢材加工业也需要与时俱进,研发新型高性能钢材。建筑以及冶金业两个行业间需要相辅相成,共同进步,推动我国的产业升级、经济发展。为提高钢结构的耐震性能,低屈服比的结构用钢也应运而生。下文就低屈服比结构用钢进行分析研究。
In recent years, with the development of building steel structure, in order to ensure the safety and economy of the building, and to make full use of the space and the requirements of the exterior appearance of the building, the demand of the construction industry for the performance of the new steel structure has also become diversified. To this end, the steel industry has invested a great deal of manpower and resources for the research and development of high-performance structural steel, and added a number of specifications for this type of steel outside the performance protection. The other hand, the developed countries and regions in the world, the construction industry will be one of the important markets for the use of steel. In order to better serve the construction market and promote the technological upgrading of the construction industry, the steel processing industry also needs to advance with the times to develop new high-performance steel . Construction and metallurgy between the two industries need to complement each other and make progress together to promote China’s industrial upgrading and economic development. In order to improve the seismic performance of steel structure, structural steel with low yield ratio has also emerged. The following article on the low yield structure of steel for analysis.
