Prestress hyperbolic paraboloid single-layer bolt sphere joint latticed shell and manufacturing method
The invention provides a prestressed hyperbolic paraboloid single-layer bolt-sphere joint latticed shell and a manufacturing method, the latticed shell comprises steel pipe rod pieces and bolt-sphere joints, the steel pipe rod pieces are connected through the bolt-sphere joints to form the single-layer latticed shell with the hyperbolic paraboloid shape, and full-curved-surface prestress is applied to the single-layer latticed shell. The reticulated shell disclosed by the invention is relatively high in in-plane and out-plane rigidity, relatively high in basic frequency and relatively small in pneumatic influence; the shape is similar to a cable net, nodes are small and compact, and the appearance is simple. The steel pipe rod pieces are selected according to the full stress optimization principle, the prestress forming principle is easy to understand, the construction method is simple, the quality is easy to control, and the structure cost is low; finite element analysis is fast in convergence, reliable in calculation and high in precision, and common commercial software can meet modeling and calculation of mechanical analysis.
本发明提供一种预应力双曲抛物面单层螺栓球节点网壳及制作方法，该网壳包括钢管杆件和螺栓球节点，所述钢管杆件通过螺栓球节点连接形成外形为双曲抛物面的单层网壳，并在单层网壳上施加有全曲面预应力。本发明的网壳面内与面外刚度较高，基本频率较高，气动影响较小；形状类似索网，节点同样小巧，外形一样简洁。按照满应力优化原则选取钢管杆件，形成预应力的原理容易理解，且施工方法简单、质量容易控制，结构成本低；有限元分析收敛快、计算可靠、精度高，常用的商用软件就能满足力学分析的建模与计算。
