Overview
This Concrete Slab on Grade (ACI 318-19) Calculator helps structural engineers determine the load-carrying capacity of concrete slabs subjected to concentrated point loads. Using the analytical method by Azzi and Laird and referencing ACI 318-19 and IBC 2018, the calculator evaluates slab behavior under various load combinations, factoring in subgrade stiffness, concrete strength, and base plate geometry. Engineers can use it to design or check slab-on-grade systems supporting columns, racks, or heavy equipment, ensuring that applied loads remain within allowable limits and that serviceability is maintained.
Presets
A preset is a ready-made configuration that instantly sets up a structural calculation with commonly used parameters, materials, and load scenarios. Each preset is tailored to specific use cases like floor joists, roof girders, or deck beams.
Why ClearCalcs?
See how ClearCalcs transforms structural calculations from a tedious, error-prone chore into an efficient, stress-free process.
With spreadsheets and clunky software
Struggle with endless spreadsheets and custom formulas.
Building codes change, but outdated software and spreadsheets don’t.
Triple-check and verify manual input at every turn.
Old software feels like a maze, with unclear settings, limited templates, and rigid interfaces.
With ClearCalcs
100+ pre-built calculators for different materials.
Every calculation comply with the latest codes and standards.
Forget the worry of “black box” calculations; verify calculators with inline formulas, codes, and checks.
Intuitive tools built to your workflow, plus unmatched customer support.
How It Works
Tired of complex calculations? ClearCalcs Calculator Library keeps it simple, secure and code-compliant – so you can calculate with confidence.
ClearCalcs offers an extensive library of easy-to-use calculators for beams, columns, and footings, designed to make structural calculations simpler and faster.
Choose from a wide range of pre-configured beam and column options, complete with automatic member sizing, so you can quickly reach reliable designs and reduce rework.
No need to copy and paste reactions between calculations! If the top calculator's reactions change, the loads being inherited onto the lower calculator will update automatically. This includes all loads such as dead, live, snow, seismic, and wind.
ClearCalcs is not only easy to use, but also easy to check! All calculations follow an easy to understand traffic light check system, with multiple levels of detail available giving you the choice of printing every step of the calculation and all code and standard references, or simply a compact, one-page print out.
