摘要
南阳玉器超市金字塔形屋顶采用了在国内应用较少的折板网壳结构,工程利用有限元理论对结构进行稳定性分析,计算考虑了几何和物理双重非线性的结构失稳全过程和极限承载力,考查了支座刚度对结构静力和稳定性能的影响。计算结果表明,金字塔形的折板网壳结构具有受力合理及经济技术指标优良的特点。
Nanyang Jade Article Supermarket pyramidal roof adopts folded-plate lattice shell structure. In this project, stability of the structure is analyzed with finite element theory, full course of structural stability loss considering geometric and physical dual nonlinearity and ultimate bearing capacity are calculated, and the influence of pedestal rigidity on structural static force and stability performance are examined. The calculation results reveal that pyramidal folded-plate lattice shell structure has many characteristics, such as reasonable stress and favorable economic and technical indices.
