Numerical modelling of the contact problem on the end-plate connections of the steel structures

This paper presents method, procedure and the developed mechanism for experimental determination of the F�� diagram for high strength bolts with 10.9 class of strength, which are used in the endplate connections of the steel stru ctures. The F�� diagram is essential as an input parameter for the "SOFISTIK" software package users, and for the real numerical modelling of contact problems in the endplate conn ections of the steel structures and obtaining the MF diagram using FEM. As well, it pr esents the comparison between the numerical method obtained from the M� Φ diagram and the MF diagram obtained from EUROCODE 3 under the given rules within the procedure.
