Tapered Gusset Plates using Custom Angle
Modeling tapered gusset plates in RISAConnection is now easier than ever. With the recent addition of the Custom Angle input, you may now enter an angle to quickly cut back a gusset edge.
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…

Eurocode lateral torsional buckling capacity is calculated per equations in Annex F in the ENV 1993-1-1:1992. This calculation uses variables C1, C2 and C3. Since there is no generic formula in the Eurocode to calculate the moment gradient factor, C1, RISA will use the widely accepted López, Yong...
The new AISC 360-16 15th Edition changes have been implemented into RISA-3D v17.0 and RISAFloor v13.0.
An update to the Cold-Formed Steel Design Codes has been added to RISA-3D v16.0 and RISAFloor v12.0. Updated Codes include:
The new British Annex (BS EN1993-1-1:2014) for the European Hot Rolled Steel material code is now available in RISA-3D v16 and RISAFloor v12.
Stainless Steel provisions are now available in RISA-3D v16 according to the AISC Design Guide 27 - Structural Stainless Steel.
You can now set the L-Torque length for the EN1993-1-1:2014 code in RISA-3D and RISAFloor. In previous versions of the Eurocode, RISAFloor and RISA-3D used the full member length as the torque length when calculating torsional buckling. Now, per EN1993-1-1:2014 Section 13.3.2, we’ve added the...
RISA-3D can design the Cold Formed Steel face-to-face channel and track sections. You can also get design of a Cold Formed Steel tube shape in RISA-3D. The Shape Selection dialog will allow you to model the built-up sections by selecting “Face to Face” shown below.
RISA-3D now supports hot rolled steel design for the Canadian market according to CSA S16-14.
