## What is CASA Plane Truss 2D?

Structural / Civil Engineering App for static elastic analysis of 2D plane-trusses.

With CASA PT-2D an engineer can create 2D structural models of plane-trusses 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.

Trusses have all member ends pinned to the nodes, preventing transfer of bending moments and requiring the structure to be suitably braced against collapse.

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 — I like this app

*2020-06-18, version 18.03*

I teach structural analysis and design.
This app is very nice.
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 — Poor help screen

*2012-11-24*

Very poor help screen, does an automatic example, but the screen display is set zoomed out so far all 6 elements look like one.
Very poor input screen for node x y and z components.
Very poor input table for element length and sizes.
Constantly crashes.

## 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.
