A estrutura é constituída por uma viga de secção em I e duas vigas treliçadas de tubos. The structure contains several imperfections and it is loaded by the force Fz. O peso próprio não é considerado neste exemplo. Determine the deflections uy and uz and axial rotation φx at the endpoint (Point 4). O exemplo de verificação é baseado no exemplo introduzido por Gensichen e Lumpe.
Este exemplo de verificação é baseado no exemplo de verificação 0122. A single-mass system without damping is subjected to an axial loading force. An ideal elastic-plastic material with characteristics is assumed. Determine the time course of the end-point deflection, velocity, and acceleration.
Uma estrutura plana simétrica é constituída por oito treliças idênticas encastradas em apoios articulados. The structure is loaded by a concentrated force and alternatively by imposed nodal deformation over the critical limit point when the snap-through occurs. Imposed nodal deformation is used in RFEM 5 and RSTAB 8 to obtain the full equilibrium path of the snap-through. The self-weight is neglected in this example. Determine the relationship between the actual loading force and the deflection, considering large deformation analysis. Evaluate the load factor at the given deflections.

O objetivo deste exemplo é demonstrar um processo irreversível causado pelo atrito. After the loading and unloading, the end-point is in a different position than where it was at the beginning. Determine the movement of the node in the X direction.
A structure made of an I-profile is fully fixed on the left end and embedded into the sliding support on the right end. A estrutura é constituída por dois segmentos. The self-weight is neglected in this example. Determine the maximum deflection of the structure, the bending moment on the fixed end, the rotation of segment 2, and the reaction force at point B by means of the geometrically linear analysis and the second-order analysis. The verification example is based on the example introduced by Gensichen and Lumpe.

A viga em consola com um perfil em I está apoiada na extremidade esquerda e é carregada com um binário. 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).
