Single Beam Calc - Calculator

The Complete Beam Calculator for Structural Analysis and Design

Single Beam Calc is a powerful and easy-to-use beam calculator for structural analysis, beam design, and section property calculations.

Visualize bending moments, shear forces, and deflections instantly. Calculate section properties, size structural members, and generate professional reports—all within a single app.

Whether you are a structural engineer, civil engineer, architect, student, or construction professional, Single Beam Calc helps streamline beam analysis, member selection, and design verification.

Works fully offline with fast, lightweight performance, making it ideal for offices, classrooms, and field use.

■ Beam Analysis

Analyze beam behavior and visualize:

• Bending Moment (M)
• Shear Force (V)
• Deflection (δ)

Supported load types:

• Point Loads
• Uniformly Distributed Loads (UDL)
• Triangular Distributed Loads
• Applied Moments

Supported boundary conditions:

• Free End
• Simply Supported
• Fixed End

Combine various loading and support conditions to model a wide range of beam configurations.

■ Section Property Calculator

Automatically calculate structural section properties from dimensions.

Calculated properties include:

• Moment of Inertia (I)
• Section Modulus (Z)
• Shear Area (As)

Supported section types:

• Rectangular Sections
• Wide-Flange Beams (I-Beams)
• Rectangular Hollow Sections (RHS)
• Circular Hollow Sections (CHS)

Ideal for preliminary design studies and section comparisons.

■ Required Section Property Calculator

Enter a target deflection limit or required safety factor and instantly determine the section properties needed to satisfy your design criteria.

Calculate the required:

• Moment of Inertia (I)
• Section Modulus (Z)
• Shear Area (As)

A practical tool for preliminary design, beam sizing, and structural member selection.

■ Member Sizing Assistance

Refine section dimensions in real time while comparing them against target performance requirements.

Visual indicators immediately show when the design criteria are satisfied, helping you quickly identify an efficient section size.
