Project / beam setup
Continuous beam
Internal column lines are modelled as simple vertical supports. The left and right beam ends can be set to free, simple or fixed.
Span
Length (m)
Spring support settings
0% behaves like a free end vertically. 100% behaves close to a stiff support.
Section selection
Enter section dimensions and the app will derive the section properties automatically.
Include section self‑weight as full-span G UDL
Loads
Beam load input
Loads are entered by load case using x positions measured from the left end of the beam.
Uniform loads
Point loads
Moment loads
Trapezoidal loads
Axial force
Positive = compression. Uses the same input units and active G/Q tab as the other loads.
Column / buckling interaction (compression only)
When N,Ed is compression, the app adds member buckling resistance and major-axis interaction checks.
Units / assumptions
Linear elastic beam analysis using an Euler-Bernoulli beam stiffness model. Positive load inputs are downward. Current input units: point loads in metric tonnes and UDL in t/m.
Stability / LTB
Check lateral torsional buckling
Supports / stiffeners

Advertisement
This Free-plan advertising space is ready for Google AdSense or a direct Ingeniarch Labs sponsor.
AdSense is not configured yet, so the fallback sponsor card is shown.
Start a clean beam, reopen a complete saved project, or adjust your calculator settings. Projects stay editable and include the calculation setup—not just the load rows.

Verification disclaimer
This calculator, its section data implementation and its engineering outputs have not yet been independently or third-party verified. A competent engineer must check all inputs, assumptions, calculations and results before design, fabrication or construction use.
Beam Calculator Studio
Version 34.3.0 - Local single-file engineering workspace.
Calculation basis
Load combinations follow EN 1990. Steel resistance and stability checks follow the implemented EN 1993 methods shown in Help and the generated report.
Section data
Published section properties are sourced from row-level metadata in the bundled section database. Unknown entries are marked as source to be confirmed.
