There are several options for calculating a semi-rigid composite beam. They differ primarily in the type of modeling. Whereas the Gamma method ensures simple modeling, additional efforts are required when using other methods (for example, shear analogy) for the modeling which are, however, offset by the much more flexible application compared to the Gamma method.
In the case of a parallel offset of the structural plane of members and surfaces and also applying an axial offset to members, for example, the function of eccentricities may be useful.
Moving loads can be generated easily with RF‑MOVE Surfaces. A library is available with load models as defined in Eurocode 1, Part 2. The input of step size, offsets at start and end, and the distance to a reference line make it possible for the user to generate user‑defined load models and influence the number of load cases generated. RF‑MOVE Surfaces generates load cases and, optionally, a result combination as an envelope of all results.
