The contact friction mechanism of beam-to-column bolted connections in steel frames and its application in finite element analysis are studied in this paper. Based on the contact friction mechanism, the contact friction theory is discussed by ANSYS software. The contact pair element and stiffness equation, the contact arithmetic and the friction model are given, The test results validate the calculation model reasonable. An example shows the application of the contact friction theory in finite element analysis of the bolted connections. It is concluded that the finite element method is an effective method to resolve the contact friction problem of beam-to-column bolted connections. Based on ANSYS software, the methods iia this paper can be used to resolve the contact friction problem in nonlinear finite element analysis of beam-to-column bolted connections.
