CASA Plane Truss 2D 1.71

CASA Plane Truss 2D - Structural Civil Engineering App for elastic analysis of general 2D plane-truss

This version of CASA Plane Truss 2D is optimized for the iPad, meaning that you can enjoy the full CASA Plane Truss 2D experience on the big screen.

Structural / Civil Engineering App for elastic analysis of general 2D plane-trusses.CASA PT-2D allows the user to create 2D structural truss models and obtain both the numerical results and graphical representation of the deflections and forces. There is an emphasis on quick and precise input of high-resolution data through graphical tap-and-drag interaction, with numeric input available as an alternative. Automatic concurrent analysis ensures that up-to-date results are conveniently available after every edit. Clear graphical representations of deflections and force envelopes are interactive with slider bars which provide the reading off of numerical results at any point along the members.Trusses have all member ends pinned to the nodes, preventing transfer of bending moments and requiring the structure to be suitably braced against collapse.Information on how to use this App can be found both in the in-built help and also on our website.=== Technical features ===* Continuous automatic real-time analysis in response to changes.* Metric & imperial units.* Integrated extensive section library:

- American: W, HP, HSS, C
- Australian: UB, UC, WB, WC, SHS, RHS, CHS, PFC, EA, UA, TFB, UBP
- Japanese: HJ
- Russian: BFB, NFB, RSC* Integrated section generator for common shapes
- Open: I/H, channel, zed, angle, tee
- Hollow: Oval, Rectangular
- Solid: Oval, Rectangular
- Calculates: Calculates: Area, Inertia, Torsional constant, Elastic moduli, and mass per unit length* Integrated material library:
- Steel, Aluminium, Concrete, Timber, Glass* Nodes may be restrained with a pinned support or roller.* Arbitrary combined loadings of point, couple, and trapezoidal loads.* Multiple loadcases.* Graphical and numerical results include:
- Reactions.
- Deflections.
- Bending moments.
- Shear forces.
- Bending stress.* Results at any position along members.
- Points of interest automatically determined.
=== User Interface features ===* Universal App - for iPhone, iPod, and iPad.* Four simple interactive screens:
- Geometry: for creating and editing nodes, members, supports, and section properties.
- Loading: for creating and editing loads.
- Results: for reading numerical results and viewing graphical deflections and force envelopes.
- Utilities: unit system choice; on-line help; load/save file; reset.* Easy and accurate graphical drag-and-tap controls:
- High precision positioning of nodes and loads by dragging with a finger.
- Drag loads along to set position.
- Drag loads and envelopes to specify magnitudes.
- Drag marker along deflected shape or force envelope to read off value.* Numeric entry available if preferred:
- Double-tap on an input variable to enter its value numerically instead of graphically.
- A built-in calculator is provided to add flexibility to numeric input.* 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 by tapping on the blue button.
- Tap on the Use buttons to pick either major or minor axis.* PDF export via e-mail of analysis results.* E-mail import/export of models.Miscellaneous improvements.Trusses have all member ends pinned to the nodes, preventing transfer of bending moments and requiring the structure to be suitably braced against collapse.Information on how to use this App can be found both in the in-built help and also on our website.=== Technical features ===* Continuous automatic real-time analysis in response to changes.* Metric & imperial units.* Integrated extensive section library:
