Steel Member and Connection Design to Eurocode Standards
Steel Component Design per Eurocode 3 — Design and verify steel members and connections with full calculation transparency.
Overview
What is STEEL express?
STEEL express is a steel component design and verification program from RUNET Norway AS, supplied in India by RAM CADDSYS. It designs and verifies members and connections to Eurocode 3 — cross-section classification, member resistance, flexural and lateral-torsional buckling, bolted joints, single- and two-bay portal frames, purlins, bracing and base anchoring — plus composite design to Eurocode 4. Reports cite the exact Eurocode paragraph behind each result.

Applications
Everyday steel member checks
Rapid Eurocode 3 verification of beams and columns for bending, shear, axial load, and buckling during day-to-day building design.
Steel connection design
Sizing and checking bolted and welded joints — splices, end plates, web cleats, and portal-frame apex/eave/base connections — to EN 1993-1-8.
Portal-frame industrial buildings
Design of single- or two-bay steel portal frames with purlins, bracing, and haunched eave/apex connections for warehouses, sheds, and light industrial structures.
Steel base and footing anchoring
Design of pinned and fixed column bases and their anchoring systems, including overturning-moment cases, tied into the supporting foundation.
Composite steel-concrete elements
Design of composite steel-and-concrete members to Eurocode 4 (EN 1994-1-1) where steel beams act compositely with a concrete slab.
Submission-ready calculation packages
Generating transparent, Eurocode-paragraph-referenced calculation reports plus DXF/PDF drawings for checking authorities, peer review, or client documentation.

STEEL express vs Steel Portal Frame EC3
Eurocode 3 tools that can design a steel portal frame — the difference is breadth versus depth on that one building type.
| Criterion |  |  |
|---|---|---|
| Scope | STEEL expressStrength: General steel component tool: beams, columns, connections, single- and two-bay portal frames, purlins, bracing, and base/footing anchoring | Steel Portal Frame EC3Purpose-built, single-workflow tool for one building type: the single-storey, single-bay steel portal frame |
| Frame analysis | Designs single- and two-bay/floor portal frames under vertical, horizontal and seismic actions | Linear-elastic finite-element analysis of the single-bay frame, with second-order effects via equivalent imperfection loads and amplification factors to EN 1993-1-1 |
| Connections | Strength: Bolted tension, shear, splice and continuity, beam-to-beam and beam-to-column joints, plus portal-frame apex/eave/base connections with or without haunches, to EN 1993-1-8 | Bolted eave, apex and column-base moment connections to EN 1993-1-8, with haunches modelled by increasing rafter-element stiffness and base plates checked against uplift |
| Foundations | Steel base/footing anchoring — pinned or fixed bases, including overturning-moment cases, with anchor/washer-plate details | Strength: Reinforced-concrete pad-footing design to EN 1992-1-1 with geotechnical checks to EN 1997-1 |
| Best for | Everyday member and connection checks across varied steel typologies, including single- and two-bay portal frames | Single-bay industrial sheds needing a fast, focused design cycle for that one typology |
STEEL express covers the broader range of steel member, connection, and portal-frame work, while Steel Portal Frame EC3 is limited to the single-bay portal-frame typology.
