Cet exemple de vérification est basé sur l'exemple de vérification 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.
Un poteau est composé d'une section en béton (rectangle 100/200) et d'une section en acier (profilé I 200). It is subjected to pressure force. Determine the critical load and corresponding load factor. The theoretical solution is based on the buckling of a simple beam. In this case, two regions have to be taken into account due to different moments of inertia and material properties.
Une poutre articulée à section rectangulaire est soumise à un chargement réparti et déplacée verticalement par excentricité. Considering the small deformation theory, neglecting the self‑weight, and assuming that the beam is made of isotropic elastic material, determine the maximum deflection.
Un mur en maçonnerie est exposé à une charge répartie au centre de sa partie supérieure. The Isotropic Masonry 2D material model is compared with the Isotropic Linear Elastic model, with surface stiffness property Without Tension in the nonlinear calculation.
Quatre poteaux sont encastrés en bas et reliés par un bloc rigide en haut. The block is loaded by pressure and modeled by an elastic material with a high modulus of elasticity. The outer columns are modeled by linear elastic material and the inner columns by a stress-strain diagram with decaying dependence. Assuming only the small deformation theory and neglecting the structure's self-weight, determine its maximum deflection.
Un porte-à-faux à inertie variable est entièrement fixé à l'extrémité gauche et chargé par une charge continue. Plastic material is considered for the calculation.
Considérez un assemblage tubulaire d'un échafaudage soumis à un effort normal et un moment. Self-weight is not considered. The material of the tube is idealized as perfectly rigid. All geometrical non-linearities are ignored. Determine the angle of deflection.
Déterminez la flèche maximale d'un bloc 3D encastré à ses deux extrémités. 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.
Déterminez la flèche maximale de quatre poteaux encastrés en bas et connectés par un bloc rigide en haut. The block is loaded by pressure and modeled by an elastic material with a high modulus of elasticity. The outer columns are modeled as orthotropic elastic material, and the inner columns as orthotropic elastic-plastic material with the same elastic parameters as the outer columns and plasticity properties defined according to the Tsai-Wu plasticity theory.
Déterminez les flèches maximales du bloc en considérant ou en négligeant l'effet de cisaillement. The square block of the isotropic material is fully fixed at one end and loaded with uniform vertical pressure.
