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.
