Broader and Deeper Calculations

Similar to Structural Toolkit, ClearCalcs has a great range of easy to use calculators for quickly designing beams, columns and footings that engineers rely on everyday.

Designed from the ground up to be fast, simple, and online, ClearCalcs is constantly being updated based on user feedback, so not only can you expect great support, but you can also look forward to a more powerful range of calculators that already includes wood, steel, concrete, wind, cold-formed steel, and portal frame analysis.

Even More Capability

With support for unlimited span continuous beams, unlimited loads, automatic unit conversion, and lightning fast portal frame analysis, ClearCalcs doesn't force you to compromise your design. Allowing for more than just gravity loads, earthquake, wind, snow, and alternate loads can also be added for an even more encompassing design.

Best of all, all ClearCalcs calculators are aware of each other, and can be dynamically linked so they share loads and reactions that automatically update to reflect changes.


"Awesome updates. I rely heavily on your program everyday, without exception. I couldn't do without the platform. Love your work."
