Overview

About the Calculator

The ClearCalcs Spread Footing Design Calculator enables the fast design and analysis of spread footings to ACI 318-14. The calculator provides fast results for bearing capacity under service loads, flexural design, one-way shear design, two-way/punching shear design, and development lengths.

Spread footings design to ACI 318-14

Easily design and analyze spread footing design using the Building Code Requirements for Structural Concrete ACI 318-14.

Fast and accurate spread footing design with easy-to-use input

Specify your footing and column geometry with ClearCalcs' easy-to-use inputs. You can specify whether your footing is reinforced as well as indicate common types of columns such as wood, concrete, steel or generic column with steel base plate.

Customizable properties for footing reinforcements

Easily specify your footing bottom reinforcement, whether they are coated with epoxy or if they have a straight or hooked end. You can also specify the number of bars on the X- or Y-axis.

Dynamically link load reactions between column and footing design

Apply shear, vertical or moment loads to your footing design with our intuitive load inputs. You can also dynamically link load reactions between structural elements, so your footing and column can easily be linked and checked for adequacy.

Traffic light checks for spread footing design

Get instant results for your footing design with our easy-to-understand traffic light checks for factored moment capacity, shear capacity and demand, bearing capacity, and development lengths.

Why ClearCalcs?

Frustration to Flow

See how ClearCalcs transforms structural calculations from a tedious, error-prone chore into an efficient, stress-free process.

With spreadsheets and clunky software

Frustration, fuss, and fragile formulas—the old way of engineering calculations that holds you back

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Building codes change, but outdated software and spreadsheets don’t.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

Effortless, efficient engineering calculations at your fingertips.

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

Your code-compliant calculator

Tired of complex calculations? ClearCalcs Calculator Library keeps it simple, secure and code-compliant – so you can calculate with confidence.

Save time with ready-to-use templates for wood, steel, and concrete

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.

Beams

Columns

Foundations

Walls

Loads

Dynamically track your load paths from roof to foundation

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.

Submit professional reports for permit review

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.
