Abstract:The advancement and development of beam string structures and the beginning of research on beam string structures in China was briefly reviewed. The latest engineering applications of representative beam string structures in China in recent 20 years were summarized. The research status and existing problems of the upper, lower and welded spherical joints of beam string structure were summarized, and the research progress and existing problems of bending resistance performance, stress relaxation and mechanical properties after high temperature of cable members were discussed. Finally, through the overview of the overall development of the beam string structure, the development prospects and research directions were proposed.
Keywords:beam string structure; cable; key joint; equivalent friction element; engineering application
