%0 Journal Article %T Numerical modelling of the contact problem on the end-plate connections of the steel structures %A Tale Geramitcioski %A Ilios Vilos %J Applied Technologies and Innovations %D 2011 %I Prague Development Center %X 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 end-plate connections of the steel structures. The F-¦¤ diagram is essential as an input parameter for the ˇ°SOFISTIKˇ± software package users, and for the real numerical modelling of contact problems in the end-plate connections of the steel structures and obtaining the M-F diagram using FEM. It as well presents the comparison between the numerical method obtained from the M-F diagram and the M- F diagram obtained from EUROCODE 3 under the given rules within the procedure. %K End-plate connection %K steel structure %K high strength bolts %K experimental F-¦¤ diagram %U http://academicpublishingplatforms.com/article.php?journal=ATI&number=4&article=425
