Structural calculators that show their code clause

Eight free NSCP 2015 tools, sorted by the order you'd actually design a building: site and soil, loads, slabs, then foundations. Every one opens a full article that explains the method and cites the NSCP section it comes from.

For planning and checking, not for permits. These tools give fast estimates. A building permit needs structural plans and computations signed and sealed by a licensed civil engineer. Always confirm figures against the full NSCP 2015 provisions, or send us your numbers to verify.

Pick your design step

Structural design runs in a set order: you can't size a footing before you know the loads, and you can't get seismic loads before you know the soil. Pick where you are.

Past step 4? Full frame analysis, member design, and detailing need a proper model, not a web calculator. See the pro tools ↓

Need it signed and sealed?

The tools get you close. For permit drawings, a full structural model, or an assessment of an existing building, work with AEDO's engineers directly. Design and plan review can be done remotely from your drawings.

FAQ

Common questions

Can I use these calculators for a building permit?

No. They are for planning, checking, and learning. A building permit needs structural plans and computations signed and sealed by a licensed civil engineer. Use the calculators to understand your numbers before you talk to one, or to sense-check a design you already have.

Which code edition do the tools follow?

NSCP 2015 (National Structural Code of the Philippines, Volume I, 7th edition). Each calculator article cites the section or table it uses, so you can check the provision yourself.

What is the difference between the NSCP Kit and the Load Generator?

The NSCP Kit is an NSCP 2015 reference app covering loads, wind, seismic, concrete, steel, and foundation provisions. The Load Generator is focused on producing NSCP 2015 wind, diaphragm/CHB, and seismic loads formatted as ready-to-paste STAAD line loads.

Can AEDO check my structural design if I am not in Negros Oriental?

Yes. Structural design and plan review can be done remotely from your drawings for projects anywhere in the Philippines. Assessments of existing buildings need a site visit, and construction work is limited to Negros Oriental.
