Foundation systems can be any combination of mat slabs, grade beams, piles and pile caps, retaining walls, spread footings and combined footings

Slabs can be any arbitrary shape with varying thickness and can include openings and discontinuities

Pedestals can be added to spread footings and slabs

Seismic loading on retaining walls per the Mononobe-Okabe formulation

Automatic meshing of slabs into well formed quadrilateral elements (NO triangular elements are created by the mesher). This is all done “behind the scenes” without any user interaction necessary, though user may optionally control the size of the mesh

Physical member used for grade beams, automatic inclusion of internally generated mesh points

Soil spring stiffness automatically calculated based on soil subgrade modulus and slab tributary area

Ability to include passive pressure and soil overburden in slab analysis

Self weight of slabs and beams is automatically calculated and may be optionally excluded in the analysis

Point loads, point moments, line loads and area/patch loads can be applied anywhere on the slab

Include Response Spectra Analysis results from RISA-3D model

Color contouring of the slabs based on: Transverse shears, Bending moments, Displacements, and Soil pressure

RISAFoundation is a complete foundation solution and operates independently or fully integrated with RISA-3D and RISAFloor.

RISA-3D, RISAFloor and RISAFoundation are so tightly integrated that they operate as one program on the same building model. Optimize the gravity system in RISAFloor, the lateral system in RISA-3D and the foundation system in RISAFoundation, with a complete flow of information both ways.

Integration support for the following versions: RISA-3D v22, RISAFloor v18, RISAFoundation v16 and RISAConnection v14

All reactions are automatically imported into RISAFoundation for design and detailing of the complete foundation system.
