Swivel Joints of Transformable Net Shells Structures
The net shells have unlimited possibilities for creating new architectural forms. The growing number of buildings constructed using this technology indicates the prospects for the use of such structures, especially in harsh climatic conditions and remote areas. The design of reticulated shells is self-supporting and has higher bearing properties compared to other types of structures. This is due to the uniform distribution of loads on all the rods of the structure, which virtually eliminates brittle fracture. The aerodynamic shape of the reticulated shells provides the best wind flow compared to other structures, which makes them stable during destructive hurricanes and tornadoes. The authors set the task to calculate and design the connection swivel node of spatial rod constructions elements; the calculations were carried out in view of geometrical and physical nonlinearity. To that effect, the solid-state model of node was created and numerical simulation was carried out. The computer simulations of the net shells structures, the use of CAD software complexes for automation of activities on stages of design and technological preparation of production are allow to reduce the time of design development, improve the quality and reliability of the design and manufacture of elements.
