Abstract
The string beam structure is a new type of space structure, which satisfies the requirements of buildings for large spans, has good application value and broad application prospects. In this paper, the influence of the three-parameter ratio of the span, the prestress value and the number of strut on the stability of the beam string is studied. The modeling of the string member is carried out by SAP2000 software. The simulation results show that the arch structure of the stringed beam has the best stability when the span ratio is 0.25. When appropriate prestressing is applied to the structural cable, the stability of the structure will be significantly improved. The number of struts is not as good as possible. Considering the influence of the struts on the structure, choose the right amount.
