Description 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 Critical Ratio (Cc), Effective Length Factor (K), Slenderness Ratio (KL/r), Allowable Compressive Stress (Sr less than Cc), Allowable Compressive Stress (Sr greater than Cc), Safety Factor, Maximum Axial Load. 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 Horizontal Shear for Concrete and Steel, Number of Shear Connectors, Transformed Section Properties, Modular Ratio, Elastic Neutral Axis. 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.
