Structural Engineering lite vs WireMind Pro

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/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 inches/ksi and mm/MPa with automatic conversion. All section and material data included. Supports both USCS and SI units. Compatible with iPhone and iPad. Pay once — no subscriptions. References: AISC Steel Construction Manual 15th Edition, AISC 360-16, AISC ASD 9th Edition, ACI 318-19, AISC Design Guide 3.

WireMind Pro is a field-first electrical calculator built around the Australian/New Zealand Wiring Rules (AS/NZS 3000) and AS/NZS 3008.1.1 cable selection — including the 2025 edition. It's made for sparkies on the tools: large, glove-friendly controls, a sunlight-readable display, and answers in seconds — fully offline, on the job site, with no signal. Every number and every citation comes from a deterministic calculation engine — never guessed. An optional on-device assistant only turns your plain-language request into calculator inputs and explains results in readable terms; it never invents a value or a clause. Everything runs on your iPhone: no account, no internet, nothing leaves the device. WHAT IT DOES • Voltage drop — AC and DC, with operating-temperature and reactance refinement • Conductor area, Ohm's law, power and unit conversions • Cable sizing, maximum demand, protective-device coordination, earthing (adiabatic), conduit fill — you enter the value from your own copy of AS/NZS 3008, the app does the derating and the math (no licensed table is bundled — private and licence-clean) • Three ways in: guided forms, a fast keypad, or just ask • Save calculations to projects; export clean, AS/NZS-cited PDFs • Pick your edition: AS/NZS 3008.1.1 2025 / 3000 2018 / 2007 / 2000 / 1991 PRICING Try every feature free for 14 days. After that, a single one-time purchase unlocks the app for good — no subscription, no recurring charges. WireMind Pro is a calculation aid. It does not replace the AS/NZS 3000 standard, a licensed electrician's judgement, or your electrical safety regulator.
