Slab

According to EN 1992-1-1, art. 5.3.1(4) a slab is a member, for which the minimum panel dimension is not less than 5 times the overall slab thickness. The slab is loaded only by bending moments and shear forces perpendicular to the centroidal plane of the slab. Detailing provisions check is performed according to EN 1992-1-1, art. 9.3.

Shell as a slab – Shell-slab

The geometry is defined similarly to the slab geometry definition.  Unlike the slab, the shell-slab can be loaded by bending and membrane actions. Detailing provisions are checked according to rules for slab (EN 1992-1-1, art. 9.3).

Wall

According to EN 1992-1-1, art. 5.3.1(7) a wall is a member, for which the following principles are not fulfilled:

  • the section depth does not exceed 4 times its width
  • the height is at least 3 times the section depth

The wall is loaded only by membrane action and detailing provisions are checked according to EN 1992-1-1, art. 9.6.

Shell as wall – Shell-wall

The geometry is defined similarly to the wall geometry definition. Unlike the wall, the shell-wall can be loaded by bending and membrane actions. Detailing provisions are checked according to detailing provisions for wall (EN 1992-1-1, art. 9.6).

Deep beam

According to EN 1992-1-1, art. 5.3.1(3) a deep beam is a member for which the span is less than 3 times the overall section depth. The deep beam can be loaded as the wall only by membrane actions. Detailing provisions are checked according to EN 1992-1-1, art. 9.7.
