Who it's for

One platform.
Every civil engineer.

Structured for students, powerful for professionals.

🎓
Students
Learn IS 456 by doing real design projects — not memorising notes. Every step explains the calculation and cites the exact clause. Finish your project in hours, not weeks.
💼
Professionals
Complete IS 456 analysis in minutes. Get PDF reports and construction drawings ready for client presentation or site — no manual calculations.
📚
Professors
Assign real design projects to your class. Every result traces to the exact IS clause — perfect for teaching, viva questions, and grading.
AI Assistant

Your personal IS 456
structural engineer.

Stuck on a result? Don't understand why a beam failed? Just ask. The AI knows every IS clause, every formula, and explains it in plain language — like a professor sitting next to you.

Why is my Beam B6 showing 91% utilisation? Should I be worried?
91% means the beam uses 91% of its allowable capacity per IS 456 Annex G. It's technically a pass — but B6 is a transfer beam carrying load from a discontinued column, so I'd recommend keeping utilisation below 80% for safety margin.

Try increasing depth from 450mm → 500mm. Want me to recalculate?
Yes please recalculate with 500mm depth
Done ✅ With 230×500mm, Beam B6 utilisation drops to 73% — well within limits. Steel area required reduces from 943mm² to 812mm². I've updated the design and the PDF report.
Ask anything about your design...
💬
Ask in plain English
"Why did my column fail?" "What does Z=0.24 mean?" "Is M25 enough for this building?" — ask anything, get a clear answer with the IS clause.
🔁
Suggests fixes and recalculates
Not just explanations — the AI can suggest a fix (increase depth, add steel, change grade) and instantly recalculate the entire design with the new values.
📖
Teaches as it explains
Every answer cites the exact IS clause. Students learn the code while designing — not after. Perfect for viva preparation.
🏗️
Knows your entire project
The AI has full context — your building dimensions, soil type, seismic zone, every member. Answers are specific to your design, not generic.

Why StructLearn Pro

Better than the alternative.

Most students are still using Excel or doing it by hand. Here's the difference.

FAQ

Questions we always get.

Yes — the complete IS 456 design engine is free. All 28 guided steps, seismic analysis, wind loads, learning modules, and certificates are free forever. You only need to upgrade (₹299/month) when you want to download the PDF report or construction drawings.
Yes. Every calculation references the exact IS 456 clause it comes from — IS 456:2000, IS 1893:2016, IS 875 Parts 1 & 2. Professors can verify every step. Many students have successfully submitted StructLearn Pro output for final year projects, mini projects, and viva examinations.
The engine is built directly from IS 456:2000, IS 1893:2016, IS 875 Parts 1 & 2, and IS 13920. All 6 load combinations per IS 456 Cl 18.2 are applied. Results have been cross-checked against manual calculations and standard worked examples. Every formula shows the clause it comes from so you can verify it yourself.
Yes — professionals use StructLearn Pro for preliminary design, checking, and client presentations. The PDF reports are structured and professional. However, for statutory submissions requiring a licensed structural engineer's stamp, you should verify the output as you would with any design software. StructLearn Pro is a design aid, not a replacement for engineering judgment.
StructLearn Pro runs in your browser on any device — phone, tablet, or laptop. However, the interactive column grid editor, full calculation tables, and PDF downloads are much better on a laptop or desktop. We recommend using a laptop for the actual design work.
Yes, cancel anytime with no questions asked. Your projects and data are always saved — you just lose access to PDF downloads and construction drawings if you cancel. You can re-subscribe at any time to get access back.
Residential and commercial RC frame buildings up to G+20 floors. Supports regular and irregular column grids, L-shaped plans, missing columns with transfer beams, and cantilevers. Isolated footings, combined footings, and raft foundations. Seismic zones II through V, wind zones I through VI, all soil types per IS 1893 and IS 875.

The Founder

Built by someone
who needed it.

The beginning

Satyam Ojha grew up in a small village in Gorakhpur, Uttar Pradesh. After finishing school there, he moved to the city for a Bachelor of Technology in Civil Engineering — and hit the same wall every student hits: the gap between IS codes and actually designing a real building.

The work

He went into practice — first as a site engineer, then structural design. Real buildings, real deadlines. Working in the field made the gap clearer: not just for students but for fresh graduates stepping into their first design role.

Australia

He completed a master's in structural engineering in Australia. It sharpened a question he had carried since his bachelor's: why does learning structural design in India have to be this hard? The knowledge exists. The codes are public. The problem was never intelligence — it was access.

The build

StructLearnPro is the tool he needed as a student and when exploring his first job. A platform that designs real Indian buildings completely per IS 456, IS 875, IS 1893 — showing every step and every clause so engineers can understand, check, and learn.

"The problem was never intelligence — it was access to the right tools and the right explanation."

Best on a laptop
StructLearn Pro works on mobile, but the interactive grid editor, calculation tables, and PDF downloads are much better on a bigger screen. Your account is saved — open on laptop when ready! 🚀
