摘要
本文通过对张弦梁结构的矢高、垂度、预应力、撑杆数量、上弦刚度及撑杆布置方式进行参数分析,研究了这六种参数对张弦梁结构力学性能的影响方式和影响效果,进而给出了实际工程中各参数的建议取值,为设计选型提供了参考依据。
Parameter analysis is studied on beam string structure including rise of arc,drop of cable,prestress of cable, number of stay bars,stiffness of up truss and arrangement of stay bars in this article.Effect of these 6 parameters on mechanical property of the structure is obtained.The results can be used as reference for designing this kind of structure.
