Application Limits of Beam Structure Models when Calculating Oblique-Angled Framework Structures in Bridge Construction

This bachelor thesis deals with the determination of internal forces of oblique‑angled frame structures in bridge construction. It is investigated to what extent the internal forces of a frame bridge with variable crossing angles can be designed using the calculation of planar beam structure models.

The aim is to determine the crossing angle up to which the simplified calculation provides sufficiently accurate results and when a more complex finite element analysis is necessary.
