Static structure analysis

Structural analysis is the most frequently used type of calculation in structural design. This can be used both analytically and with numerical calculation methods. Stationary loads are applied to structures or components in order to calculate the following parameters: 

Deformations of a double silo

In these cases, one speaks of a calculation according to the first-order theory. The system is in a stable equilibrium. According to the second order theory, it is in equilibrium in deformed position (GMNIA). A special feature of static structural analysis is stability problems, whereby the system is in an indifferent or unstable equilibrium. This can lead to a sudden failure of the structure without prior notice. Stability problems occur when the structure or component is subjected to pressure or shear stress. These include primarily:

  • bending
  • Kippentilting
  • torsional flexural buckling 
  • buckling of plates and shells
