Free tools
Quick structural calculators. No sign-in.
Browser-based mini-tools for everyday structural work. Use them freely — when you're ready for the full BIM + FEM + AI workflow, upgrade to the StructArk app.
Slab load takedown
Define a polygon slab with holes, drop columns and beams, and instantly see how the slab pressure transfers — with numbers, in kN.
OpenBeam analyzer
One prismatic beam under any combination of point, moment and distributed loads. Live shear, moment and deflection diagrams plus reactions and reference formulas.
OpenSection designer
Standard rolled shapes plus arbitrary multi-region custom geometries. Live area, principal moments of inertia, section moduli, gyradius — with a pan/zoom 2-D viewport and PNG / SVG export.
OpenLoad transfer (FE)
Sketch a slab on a grid, drop columns, place axis-aligned beams, carve holes — then read live FE shear / moment / axial diagrams plus full reactions. Export the entire drawing as SVG or PNG.
