Beams are characterized insofar as height and width of their cross section are small compared to their span. This allows applying the Bernoulli–Navier hypothesis. A strut‐and‐tie model has to be analyzed as truss. The ability of strut‐and‐tie models to determine the deformation behavior of real structures is limited as the material laws are principally limited in their capability to capture in particular the deformation behavior of compressions fields. The focus of strut‐and‐tie models is on ultimate limit loads of reinforced concrete structures. This primarily depends on the strength of the ties and struts. Deformations of strut‐and‐tie models have been a minor aspect up to now as determination of ultimate limit loads was the major issue. It has been shown for rigid‐ or elastoplastic analyses that the ultimate limit load is reached in a process whereby certain members reach their yielding strength in a sequence.
