Overview

About the Calculator

ClearCalcs' Concrete Wall Calculator is an easy-to-use online tool for designing reinforced concrete walls to Australian Standard AS 3600:2018. Built with structural engineers in mind, it allows you to quickly analyze walls for axial, shear, and bending moment capacities, ensuring your designs are safe and code-compliant. The calculator automatically applies the appropriate design method (whether the Simplified Method for walls or the Column Design Method from AS 3600) as required, saving you time and eliminating guesswork.

Axial, shear & moment load support

Ensure comprehensive concrete wall analysis. The calculator can handle combined axial (compression or tension), in-plane shear, and bending moment loads on your wall. This means you can confidently check your wall design under all key load cases in one place, instead of juggling multiple tools or manual calculations.

Automatic design method selection

Select the optimal design approach per AS 3600:2018. The tool automatically determines whether your wall qualifies for the simplified method outlined in AS 3600 or needs to be treated with the column design method (AS 3600 Section 10). This intelligent switching ensures that each wall is designed with the correct procedure, giving you accurate results without having to manually choose methods.

Customizable reinforcement options

Easily define bar sizes, spacing, and mesh reinforcement. You have full control over horizontal and vertical reinforcement inputs – specify your preferred rebar diameters and spacing, or even utilize standard mesh sheets. The calculator checks your reinforcement layout against code requirements (like minimum steel areas and spacing limits), so you can optimize your design while staying within AS 3600's detailing rules.

Shear strength verification

Ensure compliance with AS 3600 Clause 11.6 for shear. The ClearCalcs concrete wall calculator rigorously evaluates the wall's in-plane shear capacity and compares it against the limits set by Clause 11.6 of AS 3600:2018. This verification gives you peace of mind that your wall can resist lateral loads (wind or seismic) without shear failure, and that it meets the Australian code's safety criteria.

Column design support

Automatically switch to column design when required. If your wall is too slender or heavily loaded to use the simplified wall method, the calculator seamlessly transitions to designing it as a column per AS 3600 Section 10 (compression member design). This means even in borderline cases where a wall must be treated like a column, you'll get a proper design check without needing to start a separate calculation – ensuring no scenario is overlooked.

Reference mode for easy verification

Ensure complete confidence in your calculations. With ClearCalcs’ reference mode, you can see detailed step-by-step calculations, including all formulas, assumptions, and code references. This feature helps you verify every design decision, making it easier to review, validate, and document your work for internal checks or regulatory submissions. Whether you need to demonstrate compliance to AS 3600 or simply want a deeper understanding of the underlying calculations, reference mode ensures your designs are fully transparent and backed by engineering rigor.

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.
