Finite Element Modelling

built around the way structural engineers work.

Replace scattered spreadsheets, disconnected calculators and repeated manual checks with one clear workflow for design, review and engineering judgement.

Analyse

Model beams, frames, slabs, plates and structural systems with tools suited to preliminary and detailed engineering studies.

Design

Carry out concrete, steel, timber, masonry, foundation and member checks using transparent engineering calculations.

Verify

Review assumptions, governing checks, load paths and outputs without relying on black-box calculation results.

from loading to member checks, keep the logic visible.

RKALC is designed to support engineering judgement. It helps engineers test ideas, compare assumptions, verify outputs and document the basis of design decisions.

Set up the engineering problemDefine geometry, loads, materials, sections and relevant design parameters.

Analyse and designRun analysis, member design and code-based checks within the same platform.

Review and verifyCheck assumptions, outputs and governing results before using them in practice.

built from decades of structural engineering experience.

RKALC was created by a consulting structural engineer with decades of experience designing, documenting and delivering reinforced concrete, steel, timber and masonry structures.

What began as a collection of practical calculations and design tools developed for real projects has evolved into an integrated engineering platform bringing structural analysis, design, verification and education together in one place.
