Calcs.com (formerly ClearCalcs) is structural engineering calculation software that keeps every input, formula, and code reference visible inside the calculation, so reviewers can inspect the logic instead of trusting a number. Engineers design and check beams, columns, footings, connections, and full load paths across 200+ standards-aligned calculators. Coverage includes US (IBC, AISC, ACI, NDS), Australia and New Zealand (AS/NZS), Canada (NBCC), and Eurocode. Calculators are updated when the standards change, so teams are not tracking amendments in spreadsheets. Load linking carries reactions between connected members automatically. Change a load at one level and everything downstream updates, with the trail still visible. Reports export with assumptions and references attached, which is what makes them defensible in review, with a client, or years later. Used by solo practitioners through to multi-office firms. Start a free trial and run a real project calculation end to end.
