Optimization of constructions with the grids of lenticular pipes

Abstract

Abstract Presented a new technical solution, which is a highly efficient technical and economic indicators and massively used in industrial civil engineering. Development work and optimization design calculations of lattice structures using video surveillance from core pipes. Their new technical solution has been developed, the originality of which is confirmed by patent examination. Worked gussetless node connections of belts and grids with direct connection of core elements to each other without misalignments, as well as constructive eccentricities limited by 0.25 height of belt elements, which allows not to take them into account in the calculations, provides an increase in the degree of unification of the nodes of the upper and lower carrier zones designs. The whole diagram of changes in the design parameters of the lenticular pipes is given during the transformation of their cross sections from vertical to horizontal configurations, including a transition through a circular shape. The prospects of using a new technical solution in light metal structures of buildings and structures are shown. The area of its rational use is outlined, where, using alternative design of known and new solutions, a quantitative assessment of the resources of their carrying capacity is given.
