摘要
文章通过研究开口单层椭球网状空间杆系结构,考虑三种不同的“半跨”活荷载模式,推导不同的稳定承载性能,探讨了几何非线性、材料非线性对其稳定承载性能的影响。经过对比分析,得出开口单层椭球网状空间杆系结构最不利的活荷载受力模式,研究结果可为类似工程设计提供借鉴和参考。
By studying the open single-layer ellipsoid lattice space bar system structure,considering three different"half-span"live load modes,different stable bearing performance is derived,and the influence of geometric nonlinearity and material nonlinearity on its stable bearing performance is discussed.Through comparative analysis,the most unfavorable live load force mode of the open single-layer ellipsoid lattice space bar system structure is obtained.The research results can provide reference for similar engineering design.
