| Abstract: | Two braced bars beam string roof structure(BSS) is used in main entry hall of New China International Exhibition Center.The design of the roof is introduced.The stability analysis and integral calculation analysis are performed for the two braced bars BSS.The results show that the two braced bas BSS can meet the demand of strength and stiffness.Some problems such as difference between two braced bas BSS and general BSS,confirmation of pretensioning force,influence of height-to-span ratio and design of wind resistance are analyzed and discussed.Suggestions are given for the application of this structure according to larger space between two braced bars. |
