Automated Floor Layout and Optimization for Complete Building Systems

RISAFloor designs floor systems and works hand in hand with RISA-3D and RISAFoundation 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 automatically delivers RISA-3D the information that it needs for the design of lateral systems.

RISAFloor gives you the ability to design steel, concrete, cold-formed steel, masonry, aluminum and timber all in one model while RISAFloor ES allows you to also design two-way concrete slabs within a multi-material building.

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.

RISAFloor Features

RISAFloor ModelRISAFloor features automatic load attribution based on deck direction, automatic live load reductions, full floor vibration checks, full height column stack design (considering splice locations), export (and import) of CIS/2 detailing files, parent/child relationships between floors, exclusive or additive area loads, concrete rebar detailing, true spreadsheet editing, automatic code based wind and seismic load calculations and much more.

RISAFloor links to RISA-3D for the design of the lateral system and nonstandard building components, and to RISAFoundation for design of the foundation system. You can move effortlessly back and forth between these three programs, creating and modifying your building model in any manner you wish.

Design your building floor-by-floor. Graphically assign decks and area loads – RISAFloor automatically manages load distribution and calculates LL reductions per code. Create unlimited user-defined design rules – depth/width, deflection, rebar, and many others. Make changes quickly, locally or throughout your model, and see the results.

RISAFloor Model of two-story concrete buildingWhen it comes time to get drawings out the door, rely on RISAFloor. Create DXF floor plans with the design information you need: sizes, camber, studs, reactions – you call the shots. Take your drawing management to the next level with our links to Structural Desktop and Autodesk Revit Structure.

RISAFloor model of a multi-story buildingMulti-story buildings? No problem. Manage relationships between floors; define inheritance with parent-child relationships. Have RISAFloor automatically calculate wind/seismic loads. Define snow drifts, create expansion joints, check floor vibrations all within the familiar RISA environment.

And because RISAFloor integrates seamlessly with RISA-3D, every beam, column, and load is stored to a common database. Never lose track of changes. Work on trusses or transfer girders, frames or footings – work on many designs with only one model.

RISAFloor ES Concrete Slab Design Software

RISAFloor ES for Concrete Slab DesignRISAFloor ES offers all of the capabilities of RISAFloor, plus the ability to design floors as elevated concrete two-way slabs. Buildings modeled in RISAFloor ES can even be modeled with a mix of concrete and beam-supported (i.e. non-concrete) floors, and the concrete slabs can take any shape or geometry. This makes RISAFloor ES a great solution for conventional two-way slab high rises as well as Podium Slab (concrete below, wood above) buildings that other software packages are not equipped to handle. The design of elevated concrete slabs includes optimization of rebar, full code checks including punching shear, elastic deflection analysis, and T-beams.
