The topic of this thesis is, as the title says, static analysis of truss structure on the example of a pedestrian bridge. The main task is to perform a calculation where, according to the given data, the load of the girder, reactions at the points of support of the girder, forces in the rods and the required dimensions of the girder should be determined. At the very beginning, we will start with the definiton of girders and their division. We will define truss girders and the concepts of static determinacy and indeterminacy. We will deal with the notion of axial load and how internal forces occur, and then the notion of rod buckling in the elastic and plastic areas. The calculation will first determine the weight of the bridge and pedestrians and thus the total load, then the reactions in the supports and the forces in the rods. It is then necessary to check the dimensions of the girder to ensure that the strength criterion for axially loaded rods is met. Finally, with pressureloaded rods, we additionally control the stability criteria.
