【摘要】 基于有限元方法,针对三向网格型单层柱面网壳,采用三维弹性支座模型,研究了支座刚度对其整体稳定性的影响。研究结果表明,支座刚度对网壳结构稳定性的影响较为明显,在其设计和施工过程应考虑支座刚度的影响。更多还原

【Abstract】 In this paper, based on finite element method, one kind of spatial supports models is introduced and the influence of supports rigidity exerted on the stability of single-layer cylindrical lattice shells is analyzed. The result shows that the influence of the supports rigidity exerted on the stability of lattice shells is obvious and must be considered in the design and construction of single-layer cylindrical lattice shells.更多还原
