The content of the thesis is a simplified optimization of the determination of the limit coefficient of increase of the monotonic loads on the continuous beam and thus the determination of its resistance in the form of a parametric study.In solving the problem, the theory of plasticity is used only with the influence of bending moments, which is dominant in the case of vertical load of continuous beams. In the calculations, a static theorem is used to determine the load limit and the kinematic theorem is used to verify the results.The main task of the work are both numerical analysis and determination of the load on the given beam, in three stages the limit load coefficient values are determined depending on the beam resistance topology along its axis.At the end of the thesis there is a brief analysis of the achieved results of the solution.
