Why is not possible to define any eccentricity in Z-direction in my 2D model?


In a 2D model XY with the degrees of freedom (uz/fx/fy), it is not possible to define an eccentricity. An eccentricity usually results in a normal force that is not covered by these degrees of freedom.

Use caution when using ribs. In contrast to the 3D model, the effective width also changes the stiffness of the structure.

It is therefore generally better to calculate beam models in a 3D model.
