Ultimate limit state
Check bending, shear, their interaction, and the governing utilisation to EN 1993-1-1.
EN 1990EN 1993-1-1
Design a single-span steel beam to Eurocode 3
Describe the span, section, steel grade, loads, and lateral restraints. Mia checks ultimate and serviceability limit states and explains the governing result step by step.

What this skill checks
Serviceability
Calculate deflection and compare it with the agreed project or National Annex limit.
Lateral-torsional buckling
Assess member stability using the unrestrained length, moment shape, and support conditions.
Vibration screening
Estimate the first natural frequency as a serviceability hint, not a code verification.
Frequently asked questions
Which inputs does Mia need for the design?
At minimum, provide the static system, span, section, steel grade, loads, and lateral restraint. Mia asks targeted questions when a governing input is missing.
Is lateral-torsional buckling considered automatically?
Yes, when the compression flange is not continuously restrained and the unrestrained length and support conditions are known.
Which deflection limit is used?
The project or National Annex limit takes precedence. If none is given, Mia names the customary default used and flags it as an assumption.
Can I document the calculation?
CALC presents inputs, assumptions, checks, the governing utilisation, and normative references in a structured answer that can be exported as a PDF.
