## What is CASA Beam?

Structural / Civil Engineering App for single-span beams.

Caters for many beams with arbitrary loadings. There is an emphasis on quick and precise input of high-resolution data through graphical drag-and-tap interaction, with numeric input available as an alternative. Instantly available, clear graphical representations of deflections and force envelopes are interactive with slider bars for reading off results at any point along the beam, together with single-tap access to maxima/minima and other points of interest.

* Loading resolution to 2 significant figures.

* Beam lengths from 0.2 m to 40 m (6" ~ 1600").

* Loads from 0 kN to 1000 kN (0 kips ~ 200 kips).

* Arbitrary combined loadings of point, couple, and trapezoidal loads.

* Point and couple loads at any position along beam.

* Trapezoidal loads at any position and length (full or partial span) along beam.

* Various end conditions:
 - Simply supported.
 - Fixed both ends.
 - Fixed and pinned at opposite ends.
 - Left-hand and right-hand cantilevers.

 - Bending Stress.
 - Span/deflection ratio.

* Results at any position along the beam

* Points of interest automatically determined:
 - Local and global maxima & minima.
 - Zero intercept.
 - Zero crossing points.


=== User Interface features ===

* Four simple interactive screens:
 - Geometry: for entering beam length, supports, and section properties.
 - Loading: for adding, removing, and editing loads.
 - Results: for reading numerical results and viewing graphical deflections and force envelopes.
 - Utilities: for clearing model and selecting unit system (metric/imperial).

* Easy and accurate graphical drag-and-tap controls:
 - Precision of positioning with finger as high as 1 part in 2000.
 - Drag slider for beam span.
 - Tap to add a load to the beam.
 - Drag loads along to set position.
 - Drag loads and envelopes to specify magnitudes.
 - Drag a load to the wastebin to remove it.
 - Drag marker along deflected shape or force envelope to read off value.
 - Tap on points of interest for specific results (e.g. maxima/minima).

* Numeric entry available if preferred:
 - Double-tap on an input variable to enter its value numerically instead of graphically.

* Section library presented as a straightforward selection:
 - Tap on button in geometry window to open library.
 - Tap on category (e.g. British UB).
 - Tap on section size.
 - Diagram and properties will appear; tap on a Use button to pick major or minor axis.

* Custom property generator accessible in the library:
 - In library, choose custom category.
 - Diagram and properties will appear; double-tap on a dimension to edit it.
 - Properties will automatically recalculate when dimensions are changed.
 - Choose a material (optional) by tapping on the blue button.
 - Tap on the Use buttons to pick either major or minor axis.

## Key features

- Graphical drag-and-tap input
- Extensive section and material libraries
- Metric and imperial unit support
- Interactive deflection and force envelopes
- Automatic analysis of arbitrary loadings
- Results at any point along the beam

### 1/5 — Not answering to my question

*2020-05-20, version 18.02*

I need answer to my question

### 1/5 — CASA beam

*2019-09-11, version 18.02*

This app is terrible.  Don’t waste your time or money

### 1/5 — Stinks

*2017-03-11*

This app is terrible, no help option, hard to input parameters, and unclear endpoint supports.

### 4/5 — Very useful app

*2013-12-08, version 1.80*

Thanks for your handy app.
Could you please add more customisable sections to the custom geometry section of the app? E.g stiffened I-beam with double webs, stiffened I-beam with a Tee, unequal flanges I-beams, unequal flanges PFC, trapezoids, various unsymmetrical shapes etc. Thanks

### 5/5 — Fabulous app

*2013-02-12, version 1.7*

We design lifting gear and lift all sorts of gear onsite.  This app answers questions in seconds about where to sling what from where and prove it is safe.  Enjoy your 5 Stars.

### 5/5 — Best in Class

*2012-03-09, version 1.7*

Professional presentation; this is not a toy.
Very easy to use.
Uncluttered screen.
Clean visual presentation.
World sections database.
Custom sections.
Unit weight for each section (including custom sections)
Very easy to apply multiple simultaneous loads.
Great visual graphic results for Stress, Deflection, Moment and Shear (numerical values also shown)
Very easy to analyse results for the complete length of the beam.
International System or US system.

This is the App that you will really use in the field because of its ease of use and the confident feeling while using it.
Editing is a breeze.
Once you try it in the field, you won’t want to go without it forever.
This App is a must for serious civil engineers, architects, construction technicians and contractors for field work. Students should buy this App.
CASA also has a “world class” prompt service for requests or information.

### 4/5 — Very Good

*2011-06-05*

As an ME who does a variety of design, this app is very useful not only in calculating shape inertia, but also in estimating effect of complex multiple loads on beams.

### 5/5 — Superbly user friendly

*2011-03-08*

As a mechanical contractor and not a trained engineer, I needed a quick and easy to use reference to confirm the designed and on-the-fly beam choices for equipment installations I do. This program far exceeds my expectations. The user interface is intuitive and precise. The choices of material shapes are beyond comprehensive, yet simple to find or create. This app, in my opinion, really sets the standard of a well thought out utility that has managed to provide an immense amount of information in a manner that is respectful to the user. No extraneous bling and no obscure operations. This was for me, money well spent. To the developers, a sincere thank you.

### 4/5 — Casa beam

*2011-02-22, version 1.4*

Fantastic program, ideal for doing quick checks on site on your iPhone, or for primary design on an iPad. Now have to decide what one to buy next although the Space Frame 3D for the price seems a no brainer.

### 5/5 — Brilliant for the Structural Engineer

*2010-05-22*

I have been waiting for an app like this for a long time, it's the quickest most accurate tool for structural engineers to do calculations any where anytime without having access to their computers. Even in the office it is sometimes easier to use this than a computer with more time consuming software. CASA's other apps are brilliant too.
Definitely the best structural engineering apps available, and I've tried them all.
