HSS Connection Design Software Capabilities in 2025 by Steel Tube Institute

Why IDEA StatiCa stands out for HSS connections

Hollow Structural Sections (HSS) present unique challenges in connection design: limited weld accessibility, complex geometries, and stress concentrations that are often beyond the reach of simplified design formulas. IDEA StatiCa addresses these challenges directly:

• Full 3D modeling of HSS joints: Model any HSS connection—whether single, double, or multi-branch—with full consideration of geometry, openings, stiffeners, and welds.
• Code-compliance: Verify against multiple international codes and standards, including AISC, Eurocode, and other codes, with a clear view of the limits of applicability.
• Advanced stress analysis: Employ Finite Element-based methods to capture local stresses, including torsion, bending, and interaction effects, which traditional checks often miss.
• Advanced base plate & anchor reinforcement design: Unlike many other solutions, IDEA StatiCa allows engineers to design and verify base plates and anchor reinforcement simultaneously with the connection, ensuring optimal load transfer and compliance with international codes.
• Integration with BIM and FEA workflows: Easily link with ETABS, STAAD.Pro, SAP2000, and other 30+ analysis and BIM tools, keeping your HSS design consistent across the project lifecycle. You are not limited to one solution; it integrates with many. 
• Efficiency without compromise: Reduce trial-and-error iterations by instantly checking multiple configurations, weld types, and stiffener placements, saving time while ensuring safety.

In short, IDEA StatiCa transforms HSS connection design from a conservative approximation into precise, code-compliant, and verifiable engineering—helping engineers innovate without compromising safety or efficiency.
