Current Status and Prospects of Construction and Service Technologies for Prestressed Steel Structures
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.
