摘要
张弦梁结构是由单榀张弦梁结构通过不同的布置而得，单榀张弦梁结构的性能对整体结构的性能起决定性的作用，故充分了解单榀张弦梁结构的受力性能无疑是十分必要的。为此，详细分析撑杆数目、垂跨比、高跨比、拱的惯性矩和弦的预应力等因数对受力性能的影响，以供工程设计参考。
Beam String Structure (BSS) is composed of several single beam string structures through different arrangement. The behavior of single BSS plays a decisive role in the behavior of the whole BSS. So it is very meaningful to analyze the effects of factors of single BSS. The effects of the number of struts rise-span ratio, sag-span ratio, moment of inertia and prestress of string on the mechanical performance are studied in detail here, which may be a reference for project design.
