Beam Calculator

Beam Calculator offers a comprehensive suite of 34 calculators to analyze and convert key Beam and Civil Engineering parameters. Built for professionals and students, every formula is backed by AISC 360-22, ACI 318-19, and ASCE 7-22 code references displayed directly in the calculator.

Auto-fill Section and Material Pickers let you select from 39 AISC W-shapes and standard Steel, Rebar, and Concrete grades to instantly populate input fields. No manual lookup needed.

Included Calculators (Metric and Imperial Units):

Critical Bending Moments: • Rectangular Cross Section • Open Cross Section • Nonuniform Bending Gradient • Moment Gradient Factor with PASS/FAIL adequacy check per AISC 360-22

Stress and Deflection: • Maximum Stress (Axial and Bending Loads) • Maximum Stress (Large Bending Deflection) • Axial Compression and Bending Deflection • Critical Buckling Load • Stress (Unsymmetrical Bending) • Total Unit Stress and Deflection (Eccentric Loading)

Steel and Compression Calculations: • Trial Design Area of Steel • Compression Area and Depth • Nominal Moment Capacity • Adjusted Steel Area • Reinforcement Ratios (Balanced, Minimum, Maximum)

Beam Dimensions and Shear Strength: • Required Beam Dimensions • Concrete and Steel Shear Strength • Maximum Allowable Shear (Steel and Total) • Horizontal, Angled, and Vertical Stirrup Spacing • Stirrup Shear Strength and Embedment Length • Maximum Tension Steel Spacing

Key Features: • Dual unit system: USCS (Imperial) and SI (Metric) with accurate conversions • Calculation History: save, review, and add notes to past calculations • PDF Export: share professional calculation reports • Built-in Reference Tables: W-shape sections, steel grades, rebar grades, and concrete grades • Dark mode support with three appearance options • Category filter chips for fast formula navigation
