Computer Simulation of a Prefabricated Spatial Framework

The object of the study is a spatial hinge-rod structure. The research method—the analysis of the wide variability of the forms of hinge-rod joints, the economical installation process using the principle of “self-expansion” allow us to speak about the relevance of research in this direction. The article gives an overview of spatial structures and shows the pros and cons of such structures. Examples of popular nodal connections of rod structures are given. Results: development of general principles for the formation of a spatial rod structure, development of a hinge joint, a finite element coating model. As a result of the analysis of existing prefabricated buildings, the authors of the article present their surfaces main shapes. A variant of the swivel joint developed by the authors in the COMPASS-3D software package is presented, and a model of the frame is obtained. The introduction of new types of spatial architectural and structural systems into the practice of construction is the historical objectivity of the interaction of architecture and scientific and technological progress.
