| 摘 要： | 张弦梁结构已在我国大型工程中有所应用,但对该种结构的理论研究并不完善。通过分析在全跨荷载或半跨荷载作用下,初始缺陷、矢跨比、垂跨比和预应力水平对结构承载性能的影响,得出拱矢跨比基于承载性能的最优值。对张弦梁结构的设计具有有益的参考。

| Abstract: | Beam-string structures have been adopted in several large-span structures.However,theoretical analysis of this kind of structures has not been well established.The effects of the imperfections,rise-span ratio,sag-span ratio and prestressing value on the mechanical performance are researched under uniform full-span load and half-span load.So the optimal rise-span ratio of the arch is obtained.These conclusions provide some useful suggestions for the design of beam-string structures. |

| Keywords: | beam string structure imperfections rise-span ratio sag-span ratio prestressing |
