If you want to assign joists in a framing bay with an exact spacing RISAFloor will allow you to specify which side of the bay you want the program to start the spacing measurement from. Go to the Generate Beams within Bay option from the Drawing toolbar. Select the Exact Spacing of option in the...
RISA-3D allows you to append, or merge, multiple models into a single model file. This may be helpful if you model single floors in separate files and want to stack them together.
RISAFloor has the ability to apply tapered snow loads on your building’s roof to simulate drift snow loads.
RISAFloor uses the Area Load Definitions spreadsheet to define area loads available for use on a floor.
One of the most overlooked design criteria for commercial buildings is the tendency of the floor system to bounce or vibrate due to human footfalls. Excessive vibration of the floor system is a serviceability issue, and can lead to annoyance or concern from the building’s occupants.
RISAFloor has the ability to model column splices for all columns. You have the choice of a Moment or Shear splice depending upon what type of forces you want the splice to transfer. There are a few different ways to define your splices that give you flexibility in assigning them to your columns.
The latest version of RISASection, includes a powerful new DXF import feature. This feature allows the user to import any 2D geometry into RISASection for the calculation of the cross-sectional properties and the import into RISA-2D, RISA-3D or RISAFloor for use in the larger model.
There are several ways to take your RISA-3D or RISAFloor model to RISAConnection. The RISA-3D and RISAFloor end reactions can be sent directly to RISAConnection or RISAConnection can be operated from within RISAFloor and RISA-3D.
Steel connections can be designed from within RISA-3D using the integration with RISAConnection. Before you start your connection design, you’ll need to define the type of connection and assign the connections to the beams. Just follow these steps in the RISA-3D model:
