CivilKit Beams
A direct-stiffness beam solver with AS 4100 steel section checks, load envelopes, and one-tap PDF reports. Type the beam in plain English and let the AI fill the form, or build it tap-by-tap - either way, shear, moment and deflection in seconds.

Direct stiffness solver
Multi-span continuous beams, point loads, UDLs, point moments, spring supports and internal hinges, with sub-element subdivision for accurate deflected shapes.
AS 4100 steel design checks
φMs and φVv against the demand envelope, in the same screen as the diagrams. Section library covers UB, UC, PFC, RHS and SHS.
Load combinations to AS/NZS 1170
Drop loads into G, Q, W, E cases and the app builds the governing envelope - 1.35G, 1.2G+1.5Q and the rest - automatically.
AI text-to-beam
Describe the beam in plain English and the app builds the model. Optional - the manual form is always there.
PDF reports
Branded, units-correct reports ready to email to a certifier: inputs, reactions, envelope diagrams, peak values and the AS 4100 check summary.

CivilKit Beams assists a qualified engineer; it does not replace one. Outputs must be checked against project requirements, applicable standards and site conditions before use in construction. Certification and sign-off remain with the registered engineer of record.
