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.
The Transfer In and Transfer Out checkboxes in RISA’s Wall Design Rules spreadsheet help you control how forces from regions above and below openings are redistributed during design. Whether you're excluding precast elements or ignoring small segments over openings, these settings let you tailor the force path to match real-world behavior. What Do "Transfer In" and "Transfer Out" Actually Do? In RISA, wall panels automatically generate design regions above and below openings, in addition to the full-height wall segments. Transfer In → Applies to in-plane loads (axial/shear). When checked, the in-plane forces from the small regions above and below openings are transferred into adjacent full-height wall regions. Transfer Out → Applies to out-of-plane loads (bending/shear). When checked, out-of-plane forces from regions above/below openings are transferred to adjacent full-height regions. This includes: Line loads (like from floors or roofs) located directly above the region The self-weight of the wall segment for that region These forces are added into the adjacent region’s total force calculation for design. Important Note: This is a design-level adjustment only. It does not affect the stiffness matrix used in analysis. The stiffness from all regions remains in place during solution. After solving, the forces collected in the…

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...
