Foundation Design according to Eurocode 2
RISAFoundation v12 includes mat slab, concrete beam and pedestal design according to Eurocode 2. For more information, check out the video below.
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 BS EN 1992-1-1:2004+A1:2014 has been implemented in RISA-3D version 16.0 and RISAFloor version 12.0. To select this code for your design, simply open the Model Settings and under the Codes tab select BS EN 1992-1-1:2004+A1:2014 for concrete:
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.
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...
