Аннотация
Analysis of the strength of bolted joints is a common task in the design of buildings with a metal frame. As a rule, such calculations are performed by analytical methods. However, today there are many calculation programs that make it possible to analyze the strength of steel structures using the finite element method. The capabilities of such advanced CAE programs make it possible to create calculation models of flange connections with detailed elaboration. At the same time, the issue of justifying the use of computing resources and the correct balance between simplifying the model and the correctness of the results is becoming increasingly relevant. The relevance of this issue is due to the fact that detailed finite element models of the analyzed structures can reach a dimension of 105–106 elements, which, when performing dynamic or nonlinear static calculations, leads to the need for high computational resources. The article considers the need to take into account such factors as the tightening force of the bolt, the presence of the bolt body when modeling the flanged joint assembly of a steel frame (frame assembly) for subsequent static and dynamic analysis of the structure. Conclusions are drawn about the permissibility of various simplifications of the model, allowing to reduce the computing resources necessary for the calculation.
