Improved Result Access in RISA
This video tutorial will demonstrate how to find quickly review the results in RISA-3D in order to optimize the design.
In structural steel projects, the transition from design to fabrication is a common source of coordination challenges. One of the biggest pain points? Connection design. Whether it’s miscommunication on end reactions or unclear design intent, connection assumptions can break down in the gap between engineering and detailing. By using RISA-3D and RISAConnection—and leveraging direct integrations with SDS2 and Tekla Structures—structural engineers can streamline the handoff to fabricators, reduce errors, and improve collaboration. This post walks through how to support real-world coordination using these tools in practice. 1. Model and Analyze the Steel Frame in RISA-3D Start by building your structural steel frame in RISA-3D. Define geometry, assign member sizes, apply loads, and analyze the model. Once you're satisfied with the analysis results, RISA-3D provides the connection forces—axial, shear, and moment reactions—for each member end. 2. Export Connection Forces to RISAConnection Next, send selected members and their design forces to RISAConnection. This direct integration eliminates the need to manually transfer loads or recreate geometry. Once in RISAConnection, you can: Choose from a library of shear, moment, and braced connections Model the full geometry, including bolt patterns, welds, and gusset plates View pass/fail results for each limit state, with clear failure mode…

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.
RISA-3D v13 includes a new Ritz Vector Solver for the Dynamic analysis. When running a Response Spectrum analysis for seismic design, some structures experience large numbers of local modes that don’t contribute to the lateral response of the structure. The use of load-dependent Ritz vectors...
Cold Formed Steel channels are often built-up as back-to-back sections to help strengthen them. RISA-3D can design the Cold Formed Steel back-to-back channel and track sections. The Shape Selection dialog will allow you to model the built –up sections by selecting “Back to Back” shown below.
Timber design per the Canadian CSA 086-2009 design code is now available. Canadian wood member design is very similar to the US NDS member design. There are slightly different load factors, material properties, shape tables, and capacity equations, but the overall modeling procedure in RISA is the...
New codes have been added to RISA-3D v13 and RISAFloor v9, these include: AISI S100-12: Cold-Formed Steel Design Code CSA 086-09: Canadian Wood Design Code ACI 530-13: Masonry Design Code To select these codes for your design, simply choose them from the Codes tab of Global Parameters:
RISA-3D and RISA-2D come with a default list of existing moving load patterns. These are listed in the Moving Loads Library which can be viewed by clicking on the Moving Load Patterns button in the Advanced tab.
The Load Combinations spreadsheet in RISA-3D is limited to ten columns of BLC and Factor combinations. However, there are times where you may need to include additional entries to your Load Combination. To do this, you can simply “nest” your load combinations.
After solution in RISA-3D, you can use Results View Settings to view the Plate Contours graphically on your model.
