摘要
文章利用有限元软件3D3S和ABAQUS,以六边形对角布索方案建立了跨度50m,矢跨比1/5的索支撑五、六边形网格单层球面网壳和相应的单层球面网壳的数值模型,对其杆件应力比、刚度、动力特性和稳定性进行了比较研究。结果表明,该类型索支撑单层球面网壳的力学性能均优于相应的五、六边形网格单层网壳结构;索支撑五、六边形网格单层网壳的杆件分布相对较为稀疏,具有较好的建筑视觉效果。
By finite element softwares 3D3S and ABAQUS, numerical models of cable stiffened pentagonal and hexagonal latticed dome with cables in opposite angular vertexes of hexagonal grid and its corresponding single-layer latticed dome are created, and the spans and rise-to-span ratios of the two models are 50m and 1/5 respectively. The member stress ratios, stiffness, dynamic characteristics and stability are compared between the latticed dome and cable stiffened latticed dome. The results show that the mechanical performances of the cable stiffened latticed dome are better than those of latticed dome, and that the cable stiffened latticed shell with pentagonal and hexagonal grid has good architectural effect because its member distribution are relatively sparse.
