Improved input of fxk1

In Danish National Annex it is now possible to use different input methods of the characteristic flexural strength (fxk1) of brick materials. There are three possibilities on how to obtain the value:

  • set the value manually,
  • use the formula fxk1 = 0.035 * fb with filled and unfilled perpend joints, where fb is the normalized mean compressive strength of a masonry unit,
  • use the table value given by EN 1996-1-1 3.6.3. (3), as required by other Eurocode National Annexes.

Shear check

Masonry walls are often used as shear walls in smaller buildings. To support this scenario, FEM-Design now offers a possibility to check the shear of masonry walls according to EN 1996-1-1: 6.2.

New material properties

Shear design properties can be set for brick materials in the Application data of Brick material.
