Cold-Formed Steel Design Codes Update
An update to the Cold-Formed Steel Design Codes has been added to RISA-3D v16.0 and RISAFloor v12.0. Updated Codes include:
When working with RISA-3D, a structural analysis and design software, it's essential to thoroughly review your model to ensure accuracy and reliability. This checklist will guide you through the critical steps to review your RISA-3D model before analysis and design. This guide is not all encompassing for every type of model and situation and therefore are recommendations only. While this guide is not all encompassing, it is a really good start for those new to RISA-3D but also can be used to create or expand your company's review guideline/standards. Check out our guide below. Check Code Compliance: Review and confirm that the appropriate design codes and standards are selected for your project. Ensure that all code-specific settings and parameters are correctly configured, such as load factors and material properties. Units: Verify that the units used in your model match the units required for your project specifications. Check that length, force, and other units are consistent throughout the model. Application Settings: Examine machine-specific application settings and adjust them as needed for your project. Check/uncheck settings such as: Lock isolated rotational instabilities without notification. Enforce code RECOMMENDED slenderness limits (KL/r > 200, etc). Enforce code required P-Delta analysis. Section Sets Ensure that…

An update to the Cold-Formed Steel Design Codes has been added to RISA-3D v16.0 and RISAFloor v12.0. Updated Codes include:
RISAFloor v11 includes the new Area Load Query tool which allows users to visually inspect the area loads applied to a floor level.
Basic Description Pattern based skip loading has recently been added into RISAFloor beam design. This can be turned on or off using the checkbox in the Solution tab of the (Global) Model Settings shown below.
The International Code Council just released the 2018 International Building Code (IBC) in August 2017.
The Steel Joist Institute (SJI) sizes and capacities from the 44th Edition Standard Specifications Load Tables and Weight Tables for Steel Joists and Joist Girders are now available in RISAFloor v12. There were no changes from the 43rd to the 44th Editions so you’ll see that these two are grouped...
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...
