Basement Wall


The BWA+ program is used to design basement walls of reinforced concrete, which can be loaded by vertical loads and moments at the top and by earth pressure on one side. For the foundation, the simplified base pressure verification as per DIN 1054 as well as the bending and shear design are performed. The basement wall is considered as a vertical member with a pinned or restrained top and a base restrained between two continuously supported members simulating the foundation.

  • Reinforced concrete with selectable wall friction angles
  • Material quality separately selectable for the foundation, the wall, and the floor
Structural system
  • Freely selectable geometry and position of the wall
  • Type of support (pinned, partly of fully restrained) and stiffness between wall and floor slab on top
  • Geometry and continuous support of the foundation


  • Freely selectable soil parameters
  • Any number of soil layers
  • Base pressure resistance according to empirical values from DIN 1054 or specified by the user

Ground surface:

  • Horizontal, continuously ascending, or broken slope
  • Height of the earthfill for the calculation of the earth pressure


Optionally, different groundwater levels can be defined on the basement side and on the earth pressure side. The actions caused by the differential water pressure and by buoyancy are automatically derived from these specifications.


  • Any ground-surface loads in the form of area loads, strip loads, block loads, and line loads.
  • Vertical concentrated loads and concentrated moments applying to the wall head as well as concentrated loads applying to the foundation edge.
  • Free assignment of loads to types of actions according to EC 0 as well as to concurrency and alternative groups.
Earth pressure
  • Earth pressure at rest, active or any increased active earth pressure
  • Optionally with minimum or compaction earth pressure
  • Compaction earth pressure and minimum earth pressure optionally available
Reinforced concrete design of the wall and the foundation
  • Specification of the concrete cover, the reinforcement layer and the minimum diameter
  • Durability verification via exposure classes
  • Consideration of a minimum reinforcement quantity
  • Optionally, different design options for the wall and the foundation
  • Shear verification as a plate and design in the contact face optionally available
Geotechnical verifications
  • Simplified verification with base pressure resistances (either user-defined or taken from tables of DIN 1054)
