Calculation of the equivalent elasticity of a support

Elasticity coefficients are calculated based on the following formulas:

• KZ:

  k= A * E / L

• KX, KY:

  - For a roller support: k= 0

  - For a pinned support: k = 3 * E * I / L^3

  - For a fixed support: k = 12 * E * I / L^3

• HX, HY:

  - For a roller support: k= E * I / L

  - For a pinned support: k = 3 * E * I / L

  - For a fixed support: k = 4 * E * I / L

  Depending on a direction I = Iy or I = Iz.

  Note: If either the Column or Wall through two stories option is selected, k (k1 and k2)are added together.
• HZ:

  k= G * Ix / L

  Where: G = E / (2*(1+v)).

  Note: If either the Column or Wall through two stories option is selected, k (k1 and k2)are added together.

For walls, the area, the moment of inertia for bending, and the torsional moment of inertia are used according to the assumptions for the elastic support.
