大跨度短撑杆式张弦桁架结构形式的研究

Research on large-arch short strut truss string structure

结合短撑杆式张弦桁架的优点,采用有限元软件ANSYS10.0对竖直撑杆式张弦桁架和V形撑杆式张弦桁架进行计算,得出竖直撑杆式张弦桁架的受力性能好,但没有V形撑杆式张弦桁架美观的结论,从而为工程设计积累了经验。

By combining with the advantages of the short strut string truss structure, the paper adopts the finite elementary ANSYSIO. 0 to Calculate the vertical strut string truss and V-shaped strut string truss, and concludes the stressed performance of the vertical strut string truss is better, while it is less attractive than the V-shaped strut string truss, so as to accumulate experience for the engineesing design.
