Exclude Results based on Selection in RISAFloor and RISAFoundation

New to RISAFloor and RISAFoundation is the ability to exclude results by selection. Excluding results from your model is useful when there are certain elements whose results aren’t of interest to you. Removing this clutter from the results will enable you to concentrate on the elements you are most interested in.

Methods to Integrate with RISAConnection

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. Below are the two methods to send the information from RISA-3D and RISAFloor to RISAConnection. 1. With a Single or Batch solution present, take the RISA-3D or RISAFloor model to RISAConnection using the Director button in the upper right corner of the screen. 2. In RISAFloor, click the RISAConnection icon to take all of the member end reactions to RISAConnection, analyze the connections, and return connection results to RISAFloor. This all happens without opening RISAConnection. In RISA-3D, with a solution present, you can choose to Design Connections from the Solve dialogue. The member end reactions will be sent directly to RISAConnection and the connection results will be sent back to RISA-3D without opening RISAConnection. Once the connections are designed in RISAConnection, take the information back to RISA-3D and RISAFloor by pressing the Export to RISA-3D/FL button within RISAConnection. The Connections Results will be present on the Results toolbar and this spreadsheet will summarize the connections and controlling limit states for code check. With the Connection…

How to Import a Seismic Moment Connection into RISAConnection

Design for seismic connection detailing is now available in RISAConnection and you can use the connection rules within RISAFloor and RISA-3D to export a RISAConnection model. The integration will import the connection forces (and seismic detailing results) into RISAConnection for seismic moment frame connection design. From RISA-3D: First, you must apply both a “Column/Beam Seismic Moment” connection rule and a seismic design rule to the member (beam) within RISA-3D. Next, solve the RISA-3D model in order to review your seismic detailing results. If you do not have seismic detailing results in RISA-3D, then the information cannot be exported to RISAConnection. For more information about seismic detailing results, see the RISA-3D Help file topic “Seismic Detailing“. Use the Director tool to export the model into RISAConnection. When exported into RISAConnection, the program will determine the connection type, seismic system, and seismic input values based on the applied RISA-3D seismic design rule and the RISA-3D solution results. Once in RISAConnection, these cannot be changed. From RISAFloor: Apply the “Seismic Moment” connection rule to lateral members with RISAFloor (see above) or in RISA-3D. Solve the model in RISAFloor and use the Director tool to take the model into RISA-3D. Apply the Seismic Design…

Making a Time History Animation Video

Time history analysis solves for normal analysis results (joint displacements, member forces, code checks, etc.) based on loading that varies with time. For some analyses it may be useful to view an animation of the deflected shape of the structure as a function of time. This blog topic serves as a guide for users who doing this for the first time. Step 1: Applying the Load and Solving: In this example, we’ll start with TH_Seismic_frame.r3d from the Documents\RISA\Model Files\Examples folder (Load Combination 3) which applies the North – South ground motion from the 1940 El Centro earthquake. Step 2: Viewing the Deflected Shape Navigate to the View tab and select Animate Results. Choose Time History and select the appropriate Load Combination. Note: The static deflected shape can be plotted by selecting the load combination and then choosing the Time Step in the Deflection tab of the Results View Settings. Step 3: Controlling the Animation The new screen that pops up shows the animation of the deflected shape as a function of time. At the top of the screen you’ll find all the controls for this animation. Note: The Speed Slider bar also controls the total duration of the movie if…
