Shaping of buildings based on rod arches with variable geometry
Abstract
Introduction. Spatial core structures of coatings are used for more efficient industrial production of building structures, which reduces the costs of their mass production, specialization of production and rationality of design solutions. When designing spatial coverings, unique designs of single execution are used, which help to solve grandiose architectural and functional tasks. But coatings that are based on standard elements that help to create various architectural forms are also in great demand.Materials and methods. The subject of the study is a spatial architectural and structural system that is capable of implementing various design tasks, being fast-built, lightweight and having unified elements that exclude assembly welding. Such arches will find wide application from sports to exhibition complexes, thanks to their quick installation. The arch can take the shape of a circle, an ellipse, a parabola or bending in two directions, the arch can take the form of an arbitrary curve with the conjugation of curves curved in different directions.Results. The spatial arch is assembled according to the principle of a crystallographic triangulation scheme, where the upper and lower belts, braces and rods can be distinguished. A new universal joint connecting element connecting from six to twelve standard rods is proposed, which allows achieving a minimum number of standard sizes and performing ground-based manual assembly of enlarged structural elements, the spatial rigidity of the system is ensured when they are articulated together.Conclusions. The results of the present study allow us to consider such a variant of the rod spatial arch as a promising solution, as a result of the theoretical study, it was found that the main direction of improvement of spatial rod structures is the development of new nodal connections.
