CASA Intuition Brazil L +4

Structural / Civil Engineering App for aiding the intuitive understanding of the behaviour of space-frames under load.

Aimed at students, CASA Intuition allows the user to create 3D structural models and obtain both a graphical representation of the deflections and forces and also normalised numerical values for easy comparison of effects around the structure.

(Note: no actual analysis results are given.)

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.


=== General Technical Features ===

* Automatic analysis.

(Displayed property values are normalised and for comparison purposes only.)

* Integrated section generator for common shapes:
- Open: I/H, channel, zed, angle, tee.
- Hollow: Oval, Rectangular.
- Solid: Oval, Rectangular.
- Calculates: Area, Inertia, Torsional constant, Elastic moduli, mass.
(Displayed property values are normalised and for comparison purposes only.)

* Integrated material library:
- Steel, Aluminium, Concrete, Timber, Glass.

* Member ends can be rigid or pinned.

* Loads applied as point, couple, trapezoid.

* Multiple load-cases.

* Gravity (self-weight) loading.
(Numerical values are not actual; they are normalised for comparison purposes only.)

* Graphical and numerical results include:
- Reactions, deflections, bending moments, shear forces, bending stress.
- Points of interest.
- Results given all along members.
(Numerical values are not actual; they are normalised for comparison purposes only.)
