A Complete Foundation Solution

RISAFoundation gives you the ability to solve and optimize all types of foundation systems, including mat foundations, grade beams, pile caps, retaining walls, isolated spread footings and combined footings.

RISAFoundation also fully and completely integrates with RISA-3D and RISAFloor, providing a complete structural design solution. Whether running standalone or from within RISA-3D/RISAFloor, RISAFoundation provides unparalleled ease, flexibility and power for the drawing, design and optimization of foundation systems.

Automatic mesh generation, thick plate modeling and comprehensive rebar calculations and detailing are some of the many reasons why RISAFoundation stands apart.

Automatic Mesh Generation

Slabs are automatically discretized into well formed quadrilateral – not triangular – elements at a specified mesh size. Beams are automatically discretized.

Thick Plate Modeling

The thick plate method of RISAFoundation provides more realistic results than the thin plate modeling procedure found in other products.

Comprehensive Rebar Calculations and Detailing

RISAFoundation gives you the freedom to design and detail a slab in any direction. Grade beams, pile caps and spread footings are automatically designed and detailed as well. Rebar schedule and DXF export are also available.

RISA-3D and RISAFloor Integration

RISAFoundation excels as a stand alone application. Its full integration with the RISA Building System brings productivity to a higher level. Manage all project footings in one model, in one file, and within the same environment as your structure. All loads are automatically applied and all footings are optimized at once.

RISAFoundation v4 Specifications

Modeling Features

* Foundation systems can be any combination of mat slabs, grade beams, 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
* Model and design grade beams: between slabs, on slab perimeters, between spread footings and independent
* Variable soil properties possible throughout the foundation system
* Impose point supports anywhere in the model. Supports can be rigid, tension only, compression only or tension-compression spring
* Automatic generation of circular mat slabs
* Comprehensive CAD-like graphic drawing/editing capabilities that let you draw and modify as well as snap, move, rotate, copy, scale, delete, apply, mirror, etc.
* Versatile drawing grids (orthogonal, radial, skewed)
* Universal snaps allow drawing without grids
* Powerful graphic select/unselect tools including box, line, polygon, invert, criteria, spreadsheet based, with locking
* True spreadsheet editing with cut, paste, fill, math, sort, find, etc.
* Unlimited undo/redo capability and automatic timed backup
* Dynamic synchronization between spreadsheets and graphics
* Constant in-stream error checking and data validation
