## What is CASA Multi?

Structural / Civil Engineering App for static elastic analysis of 2D concatenated beams.

With CASA MB-2D an engineer can create 2D structural models of concatenated beams and obtain both the numerical results and graphical representation of the deflections and forces. There is an emphasis on quick and precise modelling with graphical interaction. Results are graphically interactive with a sliding readout of numerical results at any point along a member.

A concatenated beam is one in which each end of each beam connects to no more than one other. By way of example this includes multi-span beams and simple portal frames, but not frames with branches, ties, or bracing, nor multi-bay or multi-storey frames.

More information about this App can be found in its integrated help and on our website. The App also contains "Replay Demonstrations" which describe and enact its use.

### 5/5 — Nice app

*2020-06-18, version 18.03*

I teach structural analysis and design.
This app is good app.
You should have no problems if you follow the instructions.
My only complain is that sometimes is difficult to write the loads, but this only happens in my iphone, no problems what so ever in the ipad.

### 1/5 — civil engineer

*2012-09-17, version 1.73*

The software is designed in such a way that if you forget steps in a specific sequence the graphs of shear, moment, deflection do not show up. Instead it shows an error. My 24 dollars have gone down the waste, it requires training which I am not ready to do. 
The app is no better that any other 3 dollar app since you cannot use parabolas. waste of money.

### 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.

## Version history (last 5 releases)

### 21.05 — 2021-06-01

Maintenance update.
The app now uses the standard iOS file browser, and we recommend saving any current documents and closing the app prior to updating. On first launch, if it opens in the "Recents" files tab, then browse to "On my iPad" and then to this app's documents. If the app were not fully closed prior to updating then the documents folder may appear empty when first opened, in which case close the app in the iOS home page and relaunch it.

### 18.03 — 2018-04-09

This app has been updated by Apple to display the Apple Watch app icon.

Improved compatibility with iOS 11 and iPhone X.

### 1.87 — 2017-03-06

Fixed indication of ambiguous major axis alignment.

### 1.86 — 2017-01-04

Updates for iOS 10.
Miscellaneous improvements.

### 1.84 — 2016-06-07

Miscellaneous improvements.
