Beam and truss elements are separated in the way they take up loads. Beams take up lateral loads and moments, in contrast to trusses who take axial loads.
Beams and truss elements are important structural components in marine design. They can be used in a wide variety of modelling in both ships and offshore structures. Here are some examples of applications:
First order linear theory is used in analyzing the structures above. Large deformations and plasticity often requires more sophisticated methods like numerical approaches. The case of buckling is described under design criterias.
