 Rezime:
 Present paper describes the numerical investigation of the cold formed profiles joint assembled in a back-to-back pair. There are presented two types of joints, one for which preloading bolts used and the second type for which there were used the bracket joints with normal bolts, where the profiles are inserted in the welded plates joint. The quasi-static loading was applied in the form of concentrated force at the middle of the joint made in a simple supported beam. The F.E. models include the contact between different components and material nonlinearity. There are monitored the evolution of tension in joint, the maximum displacement of the joint beam and the identification of the potential areas for development of the local buckling. The results are based on the numerical studies achieved in the same time with the experimental tests.
