 What’s New
The new features we've added to Version 3.2 make RISAFloor better than ever. Some of these include:
- Design of concrete per the new ACI 318-2005 concrete code
- Column Stack Manager
- Complete integration with Autodesk's Revit Structure 2009
Overview
RISAFloor designs floor systems and works hand in hand with RISA-3D to provide a more complete structural engineering software solution for building design. RISAFloor will manage loads, design beams and columns, create quality CAD drawings, and constantly serve RISA-3D the information that it needs for the design of lateral systems.
 Working on one model, RISAFloor does all of the bookkeeping, letting you move seamlessly between RISAFloor and RISA-3D. RISA-3D integrates seamlessly with RISAFloor, allowing you great freedom in defining and analyzing both simple and complex systems. At any time you may move between RISAFloor and RISA-3D to make changes and see how they carry through the project.
RISAFloor has full graphical modeling capabilities that let you draw and edit your model on the screen. You may also use powerful spreadsheets that RISA is known for. Spreadsheets make non-graphical editing easy, and verification a snap. Graphic display of the model, along with applied loads and rendering, is always available. Presentation quality results are provided with interactive results review, quality rendered graphics and custom reports.
Why RISAFloor Stands Apart

- Automatic distribution of floor loads, live load reduction and self weights
- Import and export detailed CAD drawings
- Tapered area and line loads–great for snow!
- Continuous beams and absolute deflections

- Parent/Child association between similar floors
 True to scale model rendering–terrific for presentations- Multiple slabs at one elevation and 1-way or 2-way deck spans

Integrated Building Design
RISAFloor, RISA-3D and RISAFoundation are so tightly integrated 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 free and complete flow of information both ways. Lateral models are created and loaded automatically as you model and solve in RISAFloor. When you are ready to work on the lateral system, RISA-3D takes it from there.
- Lateral models created as you define & change floors
- Gravity loads are automatically applied & updated
- Wind loads (ASCE 7, IS875-87), including partial wind cases, are generated automatically
- Seismic loads (UBC, IBC, ASCE 7, CBC & IS1893), including accidental torsion, are generated automatically
- Detailed reports for Wind and Seismic load calculations
- Combine all gravity and lateral loads in standard load combinations which can be edited by the user
- All reactions (columns and walls) are automatically imported into RISAFoundation for design and detailing of the foundation system
Use all the power of RISA-3D for your lateral system. Tension-only bracing, sloping columns, openings in walls, are just a few of the possibilities. Even better, the RISAFloor, RISA-3D and RISAFoundation interfaces are the same, making them much easier to learn and use.
