Abstract
Prestressed steel structures are widely used in large public buildings,urban infrastructure,and specialized structures due to their clear and reasonable load-bearing paths,high stiffness,light weight,and ease of fabrication and installation.This paper reviewed over eighty years of domestic and international developments in prestressed steel structure construction technology,breakthroughs in material-related bottlenecks,as well as the publication of landmark projects and a series of standards and regulations.In response to the new demands of urbanization,it discussed the development and research status of prestressed steel structures,including service performance evaluation methods and multi-level performance enhancement technologies for structures in service.Finally,in line with the national strategic goals for technological innovation,the future trends of prestressed steel structures were explored,with a focus on new material applications,digital maintenance,intelligent construction,and smart control platforms.Through retrospective analysis,this paper aims to provide a reference for research and practice in the field of prestressed steel structures.
