肋环型球面空腹网壳结构的自振特性及参数分析
|
摘要
空腹网壳结构是由平板型空腹网架演化来的新型曲面空间网格结构,形式多样,具有良好的受力性能,且造型简洁美观,适应跨度更大.运用ANSYS有限元分析软件对肋环型球面空腹网壳结构进行了动力特性的研究,讨论了矢跨比、网壳厚度、腹杆截面尺寸、支座约束等参数对其自振特性的影响,得出了可用于工程实践的结论,对其抗震、抗风性能分析研究以及工程应用有参考价值.
The open web reticulated shell is developed from open web space truss,and the form is manifold.It has well received strength performance,as the appearance is succinct and esthetic.Appropriates to super-long-span.This text uses the ANSYS finite element software to carry out the analysis of dynamic characteristics of rib-type open web spherical reticulated shell.The influence of height-to-span,thickness of shell,bar section and structural constraints are discussed.The results are valuable for the dynamic response research on earthquakes and wind vibration and the engineering design of the cable-supported lattice shells.
