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. 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.
A pipe with a tubular cross-section is loaded by internal pressure. This internal pressure causes axial deformation of the pipe (the Bourdon effect). Determine a deformação axial do ponto de extremidade do tubo.
Um sistema de massa singular com amortecimento está sujeito a uma força de carga constante. 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.
Um oscilador simples é composto por massa m (a ser considerada apenas na direção x-) e pela mola linear com a rigidez k. The mass is embedded on a surface with Coulomb friction and is loaded by constant-in-time axial and transverse forces.
Uma barra de aço entre dois apoios rígidos com um intervalo é carregada por uma diferença de temperatura. While neglecting self‑weight, determine the total deformation of the rod and its internal axial force.
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. 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.
A structure made of I-profile trusses is supported on both ends by spring sliding supports and loaded by transversal forces. O peso próprio não é considerado neste exemplo. Determine the deflection of the structure, the bending moment, the normal force in the given test points, and the horizontal deflection of the spring supports.
Verifique se os resultados não são afetados pelo acoplamento de diferentes elementos dimensionais. 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.
