Steel Structure Calculator

About Steel Structure Calculator

Professional Steel Structure Calculator & Design Tool built specifically for Civil Engineers, Structural Designers, Site Engineers, Fabricators, and Engineering Students.

Accurately calculate section properties, beam load deflections, column buckling capacities, connection shear strengths, and interact with an AI Structural Engineering Assistant!

Key Features & Capabilities:

1. SECTION PROPERTIES CALCULATOR
• Instant calculation of Area (A), Moment of Inertia (Ix, Iy), Section Modulus (Zx, Zy), Plastic Modulus (Pcx, Pcy), and Radius of Gyration (rx, ry).
• Supported Profiles:
- Universal I-Beams / Wide Flange (W, S, UB, UC, ISMB)
- C-Channels (MC, PFC, ISMC)
- Equal & Unequal Angles (L-Sections, ISA)
- Hollow Structural Sections (Square, Rectangular, Circular Tubes / HSS / Pipe)
- Solid Flat Plates & Circular Bars

2. BEAM LOAD & DEFLECTION ANALYSIS
• Calculate Maximum Bending Moment (Mmax), Shear Force (Vmax), and Deflection (δmax).
• Simply Supported & Cantilever Beams.
• Load Types: Uniformly Distributed Load (UDL) and Point Loads.
• Stress checks for bending and shear compliance.

3. COLUMN BUCKLING CAPACITY (AISC & IS 800)
• Euler Critical Buckling Load calculation.
• AISC 360 & IS 800 compressive capacity evaluation.
• Slenderness Ratio (KL/r) verification for unbraced column lengths.

4. CONNECTION SHEAR DESIGN (BOLTS & WELDS)
• Bolt Shear & Bearing Strength calculation for ASTM A325, A490, and Grade 4.6/8.8 bolts.
• Fillet Weld Shear Resistance calculation based on electrode strength (E70xx / E60xx).

5. BYOK AI STRUCTURAL ENGINEERING ASSISTANT
• Bring Your Own Key (BYOK) privacy architecture. Connect Groq (Fast Llama-3.3), OpenAI (GPT-4o), Google Gemini, OpenRouter, or Anthropic Claude.
• Ask complex design questions, AISC/IS code interpretations, and design troubleshooting.
• Your API key is saved locally in encrypted storage and never leaves your device.

6. UNIT CONVERSION & STANDARD COMPLIANCE
• Toggle seamlessly between Metric (mm, kN, MPa, m) and Imperial (in, kips, ksi, ft) units.
• Compliant with AISC 360 (LRFD/ASD) and IS 800 standards.
