Get your everyday beam calculations done in minutes, with documentation a reviewer accepts the first time.
Set up the supports and loads, then check a section or find the optimal one. PolyBeam runs a full verification for bending and torsion. The documentation is a short PDF a reviewer can follow. PolyStruc runs every day at COWI, Artelia, Sweco, AFRY and NIRAS, and at 900+ universities.
Set up supports and loads for a statically indeterminate beam in the , and get reactions, shear, moment, torsion, and displacement immediately. Load combinations are optional: not required to determine the sectional forces, and can be skipped for a preliminary design too. Supports can also be modelled as plastic, capping pile reactions. .
Compare steel, timber, and concrete sections for the same beam in one model, so you can show a client the trade-offs before committing to a material. Supplier beams like Deltabeams are included alongside standard sections. Once you’ve settled on a material, PolyBeam makes it fast to test many section options: VBK generates hundreds of HSQ combinations from one setup. .
PolyBeam runs a full ULS check on steel, timber, and concrete beams: cross-section checks for bending, shear, and torsion, plus a stability check for lateral torsional buckling. The critical buckling moment is found through an eigenvalue calculation instead of a manual buckling-length lookup. .
PolyBeam checks deflection and natural frequency for steel, timber, and concrete beams. For concrete, it also checks crack width and reinforcement stress. Stiffness follows the moment distribution along the beam, giving a more accurate deflection, especially when deflection governs the design.
PolyBeam checks fire resistance for steel, timber, and concrete beams: critical steel temperature for steel, reduced cross-section for timber (EN 1995-1-2), and the Zone Method for concrete (EN 1992-1-2 Annex B). Steel can be checked both unprotected and with fire protection applied, so you only add protection where it’s actually needed. .
