. As part of the wider RISA product suite, it allows engineers to perform complex calculations within a 3D modeling environment, ensuring code compliance and structural integrity. Core Functionality Connection Types
Canadian Standard for the Limit States Design of Steel Structures. The Step-by-Step Integrated Workflow
When global frame geometry changes, engineers must manually recalculate every affected joint.
Input the sizes of the structural members. For a beam-to-column connection, you will specify the column shape (e.g., W14x90) and the beam shape (e.g., W18x35). Step 3: Configure the Connection Components risa connection software
Full compliance with the latest steel construction manual. CSA S16-19 Support: Updated Canadian standard compliance.
is a specialized structural engineering software designed for the efficient modeling and design of hot-rolled steel connections. By automating complex limit state checks and providing a highly visual interface, it bridges the gap between general structural analysis and the detailed requirements of connection fabrication. Key Features and Capabilities
When paired with or RISAFloor , the workflow becomes fully integrated. Engineers can design a complete multi-story building frame, run the global wind or seismic analysis, and then group joints to export directly into RISAConnection. The software automatically extracts the governing load combinations and member sizes, eliminating manual data entry. BIM and Detailing Interoperability Step 3: Configure the Connection Components Full compliance
Unlike "black box" FEA tools, RISAConnection allows engineers to override assumptions. You can adjust bolt slip coefficients, control which element yields first, and specify whether welds are field or shop.
RISA Technologies is committed to ongoing research and development, continually enhancing and expanding the capabilities of RISA Connection Software. Future developments are expected to include:
Future versions of connection design software may incorporate machine learning to suggest the most efficient connection type or configuration based on a set of loading conditions and geometric constraints. This could move beyond simple optimization to generative design, where the software proposes solutions the engineer might not have considered. control which element yields first
Designing Special Moment Frames (SMF) or Intermediate Moment Frames (IMF) requires compliance with strict AISC 341 seismic regulations. RISA Connection evaluates complex seismic failure modes, including: Panel zone shear yielding Strong-column/weak-beam compliance Prequalified connection geometry limitations Hollow Structural Sections (HSS)
You begin by modeling your structure—assigning member sizes, loads, and load combinations—in RISA-3D or RISAFloor. You can also define general "Connection Rules," such as whether a connection should be bolted or welded.

For engineers working in high-seismic zones (D, E, F), RISAConnection fully supports Special Moment Frames (SMF) and Special Concentrically Braced Frames (SCBF). It forces the "weak-beam/strong-column" ratio checks and properly handles protected zone requirements for welds. It will automatically flag a connection that violates AISC 341 ductility requirements.
