Residual Rigid Response (Dynamics)
When running a Response Spectrum analysis for seismic design, the response for high frequency modes can be included without solving for their individual mode shapes. This is often done to save analysis time and memory. This topic discusses some of the technical background and gives references for...

What Loads Transfer from RISAFloor to RISA-3D?
RIAFloor designs the gravity system and then integrates with RISA-3D to design the lateral system. Only the lateral members are taken from RISAFloor over to RISA-3D. The loading is automated in this integration so one of the most common questions is: what loads are transferred when switching from...

How do you add Shear Caps to columns?
Per the ACI, you can add a Shear Cap to your column to increase the shear strength of the slab. In RISAFloor ES two-way slabs, adding a shear cap will thicken the plates around the column automatically. The Shear Cap will affect the Punching Shear and the One-Way shear calculations. As you draw the...

How to Create a Custom Shape in RISA-3D
There are multiple options in RISA-3D and RISAFloor to create a custom shape not available in the program databases. The first, is to utilize RISASection in order to create cross-sections, calculate section properties and import the shape directly into RISA-3D. For more information on integrating...

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...

Capture Animation in RISA
This video will demonstrate how to capture the animation from RISA-3D into a movie format. The deflected shape, moving loads and mode shapes can all be shown as a animation. This feature will now allow you to export this animation to a AVI format.

Include Moving Load in Batch Solution
With the new release of RISA-3D v13.0, you now have the ability to include moving load combinations in a Batch solution. Just select which load combinations you want included in the Batch solution using the “Solve” checkboxes in the Load Combinations spreadsheet.
