AISC CODE REFERENCES
Every formula links directly to AISC and ACI clauses — AISC 360-16, AISC ASD 9th Edition, ACI 318-19, and AISC Design Guide 3.
PASS / FAIL CHECK
Instant visual adequacy check with demand/capacity ratio — green for PASS, red for FAIL.
AISC SECTION PICKER
Browse W-shapes (AISC 15th Edition) and auto-fill section properties instantly.
REFERENCE TAB
Built-in library with W-sections (W4–W44), ASTM materials (A36, A992, A572, A500, A325, A490, F1554), weld electrodes, concrete grades, and codes.
USCS & SI UNITS
Switch anytime between USCS (in, kip, ksi) and SI (mm, MPa) with automatic conversion.
All section and material data included. Supports both USCS and SI units. Compatible with iPhone and iPad. One-time purchase — no subscriptions.
