RISA Software


STRUCTURAL DESIGN LAB - RISA Software

Fast, Accurate, Productive – just a few ways engineers describe RISA-3D. Easily the most popular general 3D analysis/design software available, our intuitive interface and familiar spreadsheets help you solve your next problem in minutes, not hours. Packed with the most current steel, concrete, cold-formed steel, aluminum and timber design codes, RISA-3D gives you the tools to tackle multi-material projects with confidence. RISA-3D also integrates seamlessly with RISAFloor and RISAFoundation, including links to top detailing, drafting, and BIM packages for a complete building design solution.

RISA-3D INTEGRATION: RISA-3D is the heart of the RISA Building System, integrating with six other RISA programs to offer a complete structural solution.

RISAFLOOR + RISA-3D + RISAFOUNDATION

RISAFloor designs a building quickly with a graphical interface that allows you to lay out your columns, beams and walls floor-by-floor. The integration between RISAFloor and RISA-3D allows you to design the gravity system in RISA Floor and take the lateral system into RISA-3D to design for wind and earthquake loads. All the reactions from the gravity and lateral members are brought into RISAFoundation for design of the footings, slabs and grade beams.

RISA-3D + RISAFOUNDATION

The integration between RISA-3D and RISA Foundation allows you to use your base reactions from any RISA-3D model to design mat slabs, combined foundations, spread footings and grade beams.

RISA-3D + RISACONNECTION

Assign your connections to your member ends quickly within the familiar RISA-3D interface. Run the connection design and view results all in the same model. Changes in forces are automatically updated.
