DIN EN 1993‑1‑1 provides various design methods for standard stability analysis of steel structures, taking into account stability problems. The subject of this master thesis is a comparative study of these design options with regard to the calculation effort and the cost-effectiveness, using an example of a trough structure as a truss structure.
Based on a presumption of principal possibilities to perform stability analyses according to DIN EN 1993‑1‑1, these were applied to the design of the upper chord of a representative single-span railway bridge constructed as a trough without the upper horizontal bracing. In addition to the actual and preliminary design of the essential structural components of the bridge superstructure, this study focuses primarily on the stability analysis of the upper truss chord. The stability of this upper chord was analyzed on the entire spatial model as well as on the related structural models.
