## What is Structural Engineering Calc.?

Structural Engineering Calculator delivers 59 AISC and ACI structural formulas with instant results, demand/capacity checks, a built-in AISC section database, and material references — all in one app. Whether you’re on site, in the office, or reviewing drawings, every calculation you need is in your pocket.

59 STRUCTURAL FORMULAS

COLUMNS

BEAMS
Shear Capacity of Flexural Members, Allowable Bending Stress (Compact and Noncompact), Moment Gradient Factor (Cb), Allowable Flange Bending Stress, Plastic Moment (Mp), Lateral Unbraced Lengths (Lp and Lr), Limiting Buckling Moment (Mr), Nominal Moment (Mn), Critical Elastic Moment (Mcr), Allowable Shear Stress, Beam Deflection for UDL and Point Load.

BASE PLATES
Base Plate Area, Plate Thickness, Bearing Pressure, Flange and Web Thickness, Plate Dimensions N and B.

COMPOSITE BEAMS

CONNECTIONS
Allowable Shear with Tension Field Action, Allowable Bearing Stress for Rollers and Rockers, Axial Stress for Concentrated Loads, Allowable Bearing Stress on Fasteners, Number of Shear Connectors, Total Horizontal Shear.

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.

### 1/5 — Rather disappointing

*2019-03-14*

No code references, this is quite useless when you are asked to enter all parts of any equation. How is that time saving?

**Developer response:** Thank you for your feedback. It appears you're using Version 5.1. Kindly update to Version 6.4, which includes the new Engineering Reference Library and Smart Auto-Fill features that significantly reduce manual data entry and save time.
