The orthotropic behaviour "Masonry" is basically the same as orthotropic behaviour “Standard”
Difference is in new item "Coeff. off reduction for arching effect". By this coeff. parameter "d33" of standard orthotropy is multiplied.
By this coeff. it is easy to reduce arching effect in masonry wall. Default value is set on 0,01. Range can be <1 ; 0,0001 >.
Note 1: This type of orthotropy is automatically set when "Masonry Wall" is used in project.
Note 2: The name of this orthotropy consist of "Name_thickness of wall_material of wall" .
Note 3: The smaller value of shear stiffness reducing coefficient means the smaller the horizontal load carrying capacity of the wall.
