Beam Analysis, Column Buckling & Natural Frequency Calculator
Single Beam Calc is a free structural engineering app for beam analysis, column buckling analysis, and beam natural frequency analysis.
Quickly and accurately calculate bending moments, shear forces, deflection, section properties, buckling loads, and natural frequencies.
■ Key Features
1. Beam Analysis (Graphs & Point-by-Point Results)
Analyze bending moment (M), shear force (Q), deflection (δ), and stress with high accuracy.
• Visualize beam deformation and internal force distributions using interactive graphs.
• Automatically identify maximum and minimum values, or inspect displacement and moment at any position using a slider or direct coordinate input.
• Supported loads: Point Load, Uniformly Distributed Load (UDL), Triangular Distributed Load, and Applied Moment.
• Supported support conditions: Cantilever, Simply Supported, and Fixed support combinations.
2. Column Buckling Analysis
Calculate critical buckling load and buckling stress based on the Euler, Johnson, and Rankine theories using the column slenderness ratio (λ).
• Instantly evaluate structural safety with safety factor calculations.
• Select the effective length factor (K-factor) for various end support conditions.
3. Natural Frequency Analysis
Calculate the first through third natural frequencies (Hz) using Euler-Bernoulli beam theory while considering material density.
• View calculation formulas, substituted values, and intermediate steps to verify engineering calculations.
4. Section Properties & Optimization (Back Calculation)
Automatically calculate section properties such as Moment of Inertia (I), Section Modulus (Z), and Cross-sectional Area (A) for rectangular, H-beam (I-beam), rectangular hollow, and circular hollow sections.
• Determine the required section properties from a target deflection or required safety factor.
• Optimize section dimensions in real time.
5. Professional Reports & Gallery
Generate organized report images including calculation conditions, structural models, graphs, and result summaries.
• Save reports in the built-in gallery.
• Share reports via email or social media.
• Delete reports when no longer needed.
6. Flexible Units & Multi-language Support
Designed for engineering projects worldwide with flexible unit systems and multilingual support.
Supported Units
• Length: mm / m / in / ft
• Load: N / kN / lbf / kgf
• Density: kg/m³ / g/cm³ / lb/ft³
• Stress: N/mm² (MPa) / GPa / psi / ksi
Supported Languages
English, Japanese, Spanish, Chinese, Portuguese, Indonesian, Korean, Hindi, and Vietnamese
■ Recommended For
• Structural engineers
• Civil and architectural engineers
• Mechanical and plant design engineers
• Construction supervisors who need quick structural verification on site
• Students studying structural mechanics and engineering
Works completely offline with fast, lightweight performance.
Whether you're designing structures in the office or studying structural engineering, Single Beam Calc is your reliable engineering companion.
