Steel Member Design

Check single and multi-segment steel members for major and minor axis bending, axial force and shear, with visual member configuration and detailed design reports.

NewAnalysis-file import from SAP2000, ETABS and SPACE GASS: bring member geometry and force tables into your design, then select the member and load cases to check. Native ETABS and SPACE GASS exports need conversion to supported table formats. View export requirements.
  • NZ and Australian steel sections, with member and restraint visualization
  • Segment forces from member force diagrams
  • Summary, standard and detailed reports with PDF export

Built for checking

Everything you need to sign off a design

Code-referenced checks

Capacity checks reference the code clause or design guide check they come from, with clear pass / fail results.

Calculation reports

Summary, standard and detailed reports you can export to PDF for your project records.

2D and 3D drawings

Elevations, sections and an interactive 3D model, generated from your connection inputs.

Analysis-file import

Bring member geometry and forces from SAP2000, ETABS and SPACE GASS tables into member design.
