Una struttura costituita da un profilo a I è incorporata nei supporti delle forche. The axial rotation is restricted on both ends while warping is enabled. The structure is loaded by two transverse forces in the middle. The verification example is based on the example introduced by Gensichen and Lumpe.
Una trave reticolare piana composta da quattro aste inclinate e un'asta verticale è caricata nel nodo superiore per mezzo di una forza verticale e una forza fuori dal piano. Assuming the large deformation analysis and neglecting the self-weight, determine the normal forces of the members and the out-of-plane displacement of the upper node.
Un tubo con una sezione trasversale tubolare è caricato dalla pressione interna. This internal pressure causes axial deformation of the pipe (the Bourdon effect). Determine the axial deformation of the pipe endpoint.
Un sistema monomassa con dashpot è soggetto a una forza di carico costante. Determine the spring force, damping force, and inertial force at the given test time. In this verification example, the Kelvin--Voigt dashpot (namely, a spring and a damper element in serial connection) is decomposed into its purely viscous and purely elastic parts, in order to better evaluate the reaction forces.
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 di acciaio tra due supporti rigidi con uno spazio vuoto è caricata da una differenza di temperatura. While neglecting self‑weight, determine the total deformation of the rod and its internal axial force.
Una struttura intelaiata a due piani a campata singola è soggetta a carichi sismici. The modulus of elasticity and cross‑section of the frame beams are much larger than those of the columns, so the beams can be considered rigid. The elastic response spectrum is given by the standard SIA 261/1:2003. Neglecting self-weight and assuming the lumped masses are at the floor levels, determine the natural frequencies of the structure. For each frequency obtained, specify the standardized displacements of the floors as well as equivalent forces generated using the elastic response spectrum according to the standard SIA 261/1.2003.
Questo esempio serve come dimostrazione del vincolo del diaframma. The application is shown on a two-story structure. The structure is loaded by means of lateral forces according to Figure 1. Determine the maximum deflection of the structure ux in the direction of the loading forces using both the diaphragm constraint and the plate model of the floor.
Dimostra che l'accoppiamento di diversi elementi dimensionali non influisce sui risultati. A cantilever with a rectangular cross-section is fixed at one end and loaded at the other by concentrated forces. Neglecting its self-weight and assuming only small deformations, determine the cantilever's maximum deflections.
