This thesis discusses strength analysis of beam element structures with use of superelements. It analyses and solves simple structure made of bar and beam elements. The derivation of superelement equation in explained followed by a solution of a simple example with its use. With a help of superelements, assembled into the assembly, a realistic structure consisting of several repetitive structures is resolved. In the end the superelement is reconstructed and the stresses in the elements within the superelement are calculated. The solution is verified with ABAQUS software package.
