COMPUTER-IMPLEMENTED METHOD FOR SIMULATING BEHAVIOR OF A SCREW CONNECTION BETWEEN METAL COMPONENTS OF ENGINEERING STRUCTURES

摘要

A simulation of real behaviour of a screw connection of metal components uses a finite elements method to determine suitable elements for building construction joints and their arrangement, and to determine their parameters, wherein the method uses models for simulation of contact between plates as well as shear load of a screw connection and axial load of the screw connection.

1. Computer-implemented method of simulation of real behaviour of a screw connection of metal components in building construction comprising replacement of metal components of building construction with plates of shell components which are simpler in shape and modelled by a finite elements method in such a way that the plates comprise a number of elements interconnected via mesh nodes, wherein the plates and mesh nodes comprise at least a first plate comprising at least two first nodes and a second plate comprising at least two second nodes, and wherein the method comprises a model for simulation of contact between the plates, wherein the method further comprises a model for simulation of shear load of a screw connection and a model for simulation of axial load of the screw connection, for transfer of force and deformation load from the first nodes to the second nodes, and wherein the model for simulation of shear load of the screw connection is nonlinear.
