L'esempio di verifica descrive i carichi del vento in diverse direzioni del vento su un modello di un gruppo di edifici. The model consists of eight cubes. The velocity fields obtained by the RWIND simulation are compared with the measured values from the experiment. The experimental data are measured using a thermistor anemometer in the wind tunnel.
L'esempio di verifica descrive i carichi di pressione sulle pareti di edifici in disposizione in tandem situati a livello del suolo. The buildings are simplified to rectangular objects and scaled down while maintaining the elevation ratios. The pressure distribution on the walls of the model of a medium-high building was conducted by an experiment. The chosen results (pressure coefficient Cp) are compared with the measured values.

Una membrana è tesa mediante precompressione isotropa tra due raggi di due cilindri concentrici che non giacciono in un piano parallelo all'asse verticale. Find the final minimum shape of the membrane - the helicoid - and determine the surface area of the resulting membrane. The add-on module RF-FORM-FINDING is used for this purpose. Elastic deformations are neglected both in RF-FORM-FINDING and in the analytical solution; self-weight is also neglected in this example.

Un oscillatore semplice è costituito dalla massa m (considerata solo nella direzione x) e dalla molla lineare di rigidezza k. The mass is embedded on a surface with Coulomb friction and is loaded by constant-in-time axial and transverse forces.
Un'asta con una sezione trasversale quadrata è fissata all'estremità superiore. The rod is loaded by self-weight. For comparison, the example is also modeled with the concentrated force load, the value of which is equal to the gravity. The aim of this verification example is to show the difference between these types of loading, although the total loading force is equal.
Una parete in muratura è esposta a un carico distribuito al centro della sua sezione superiore. The Isotropic Masonry 2D material model is compared with the Isotropic Linear Elastic model, with surface stiffness property Without Tension in the nonlinear calculation.
Un'asta con le condizioni al contorno date è caricata dal momento torcente e dalla forza assiale. Neglecting its self-weight, determine the beam's maximum torsional deformation as well as its inner torsional moment, defined as the sum of a primary torsional moment and torsional moment caused by the normal force. Provide a comparison of those values while assuming or neglecting the influence of the normal force. The verification example is based on the example introduced by Gensichen and Lumpe.
Una trave di legno rinforzata da due piastre di acciaio alle estremità è caricata da pressione. The wood fibers are parallel to the upper loaded side of the beam. The plastic surface is described according to the Tsai-Wu plasticity theory.
Uno sbalzo con profilo a I è supportato sull'estremità sinistra e caricato dalla coppia. The aim of this example is to compare the fixed support with the fork support and to investigate the behavior of some representative quantities. Comparison is also made to the solution by means of plates. Small deformations are considered, and the self-weight is neglected. Determine the rotation in the midpoint of the cantilever, and in case of the member entity with warping, determine the values of the primary torsional moment, the secondary torsional moment, and the warping moment both on the left end (point A) and the right end (point B).

The block is divided in the middle: the upper half is made of an elastic material and the lower part is made of timber - an elasto-plastic othotropic material with the yield surface described according to the Tsai-Wu plasticity theory. The block's middle plane is subjected to vertical pressure.
