The usual procedure for modelling structures in PLAXIS v8 is to introduce plates, which are one-dimensional beam elements. This way, the results are beam deformations and cross-section forces that will allow the calculation of stresses with post-Plaxis procedures. However, the introduction of one-dimensional elements within two-dimensional soil elements requires the assumption of simplifying hypothesis. As recommended in PLAXIS v8 Reference Manual, this approach should only be used to model the behaviour of slender walls, plates or thin shells.
