In this paper a numerical analysis of metal swing structure, composed of rigidly bonded metal elements having an annulus cross section, has been carried out. The introduction consists of an explanation of lattice constructions as bearing structures, while the second chapter consists of the classification and explanation of the concept of static degree of uncertainty. In the third chapter, a swing is described as a load-bearing structure, the dimensions are defined and the profile of the tubular element is being chosen, with which the calculation continues. The fourth chapter consists of the description of the matrix displacement method used for analytical analysis of this task, while in the fifth chapter the finite element method is described and the verification of selected finite elements in a simple example is being performed. Chapter Six is devoted to the calculation of the metal structure of the swing in which the case of static load is being performed initially using the matrix displacement method and the numerical method of finite elements, followed by a comparison of the results and by the selection of finite element with which the rest of the task was analysed. Also, the analysis was carried out in the case of a dynamic load using quasistatic principle, considering the two swing positions, i.e. the unmounted position and the 45 degree displacement position. Strength test was performed and a graphical comparison was made for all three load cases. In the final part, a conclusion was made based on the conducted analysis and the idea for possible reconstruction was mentioned.
