Structural Engineering lite vs Culvert Studio

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.

Culvert Studio is a free, educational showcase of our engineering-software capabilities — built to demonstrate the kind of tools we can create for professionals in civil engineering, drainage, stormwater, and hydrology. WHAT YOU CAN EXPLORE - Rational Method + Manning's equation for peak-flow and culvert sizing - Recommended culvert size, design flow, and velocity — in seconds - Inlet/outlet control analysis with performance curves and headwater checks - Multi-barrel, orifice, weir, and tidal-tailwater analysis for coastal culverts OFFLINE CANADIAN IDF DATA - 565 IDF weather stations across all 13 provinces and territories - 28,900+ data points — rainfall intensity/duration/frequency curves, fully offline - No internet required at the job site VISUALIZE & VERIFY - Interactive 2D/3D culvert profile with design-flow animation - Velocity, HW/D, and compliance checks against provincial drainage manuals (ON, AB, BC, SK, MB, QC) - Save projects and calculations; export reports as PDF or GeoJSON/KML MORE THAN A CALCULATOR - Bridge hydraulics, fish passage, detention, channel, and drainage-network tools - Environmental data integration: tidal (CHS IWLS), snow (ECCC), hydrometric (WSC) - Bilingual English / Français AN EDUCATIONAL DEMONSTRATION Culvert Studio is provided as an educational, experimental showcase of what we can build — not as a substitute for professional design software. Always have results verified by a qualified engineer. Built for Canadian conditions. Works offline. If you work in civil engineering, drainage, stormwater, or hydrology, we'd love to hear from you.
