Modeling node screwing thin perforated steel profiles by finite element method

In this paper, the main methods of modeling bolted connections, is considered the most appropriate way of modeling in the software package available for an average engineer. A method for the construction of three-dimensional design scheme of finite elements is considered an example of modeling the contact problem with the use of three-dimensional finite element analysis. This modeling method can be used for modeling a screw connection there, in the design of structural elements of perforated thin-walled steel profiles.
