Nos apoios da forquilha está integrada uma estrutura constituída por um perfil em I. 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.
Uma treliça plana constituída por quatro barras inclinadas e uma barra vertical é carregada no nó superior através de uma força vertical e uma força fora do plano.

Uma membrana é esticada através de um pré-esforço isotrópico entre dois raios de dois cilindros concêntricos que não se encontram num plano paralelo ao eixo vertical. 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.

A estrutura de pórticos de dois pisos está sujeita a cargas sísmicas. 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.
Este exemplo serve para ilustrar o plano. The application is shown on a two-story structure. The structure is loaded by means of lateral forces according to Figure 1.
