Numerical Analysis of the Connection of Light Frame Elements in the Sunday System Technology

Abstract

The work is devoted to the numerical analysis of connections of light frame elements in the Sunday system technology. The analyzed technology is described, which in the light of the requirements in terms of structure mechanics as well as more and more stringent energy efficiency is an economical and effective solution. Complex numerical calculations require the introduction of appropriate input data to create computer models. In order to perform the simulation, the influence of the adopted schematic characterization of the material on the course of the stress-strain curves obtained by numerical analysis using the Ansys Reaserch 2021 program based on the finite element method was presented. The authors described the procedure for performing numerical analysis, taking into account material nonlinearity. The material models used for this type of calculations were also noted. On the example of a connection of elements of a light frame structure, the influence of the adopted material characteristics on the result of the obtained numerical calculations is presented.
