Connection Study Environment is a revolutionary software program for the design, verification and check of steel connections, allowing free component positioning in 3D space.
Developed by Castalia srl and represented by CCS in Greece and French speaking countries in Europe and North Africa, the software allows the design and the computation of simple to most complicated 3D steel connections according to several design codes, such as:
Eurocode 3 EN 1993-1-8,
British Standards 5950 Limit state,
American Standards (AISC-ASD & AISC-LRFD),
Indian Standards (IS 800 WS & IS 800 LS),
Italian Standards CNR 10011 (AS & LS) and
Russian Standard SNiP.
The software has been continuously developed since the 90’s and it has grown to become a worldwide unrivaled product.
Available versions: STANDARD and FULL
The STANDARD version has all the available typical nodes, and moreover it allows to freely create new nodes, that is freely adding and removing components, freely placed in 3D space. By using STANDARD version you can create nodes freely. The STANDARD version, however, does not allow to parameterize new nodes, and therefore to create one’s own parameterized nodes.
FULL version has all the functionalities with no limitation. In particular: it has all the available typical nodes, it allows free positioning of components, it is used to study and design new cross sections quite freely, it allows new nodes parametrization, according to one’s needs.
You have a “typical” connection (as those covered by the Standard) but with non “typical” loads (out-of-plan bending and shear, torsion, eccentricity, etc.).
You wish to verify the connection behavior outside of the framework given by the Standard (ex. allow local plastic strains).
You have a non “typical” connection (not covered by the Standard) with “typical” or “non-typical” loads.
You have a multi-planar complex 3D joint.
Basic working steps:
Construct the 3D real node.
Select a component or the whole node.
Run FEA for only the selected component or the whole node.
Review the calculated action on components.
How C.S.E. works:
Import geometry and member forces from FEA programs or build directly in CSE (standalone). Available interfaces: SAP2000, STAAD PRO, RISA 3D, STRAP, MIDAS, SARGON. Possibility to add more interfaces according to customers’ needs.
In case of imported finite element global mode, C.S.E. automatically recognizes the sets equal joints in the structure, which can be computed all in a single run, but considering all the combinations for each single instance of the joint.
User is free to define the connections in space by adding the components (plates, cleats, bolts, welds) rotating them, moving and shifting them, cutting them, or modifying them according to his needs.
Take advantage of a set of 786 predefined parametric connections to quick model some parts of complex joints.
Launch the automatic design checks according to the Standard or choose the possibility to carry out FEA checks.
“Teach” C.S.E. to include in the verifications any user customized checks.
Option to choose FEA calculations for single components, sets of components or full joints.
Option to choose linear, nonlinear, unilateral contact and buckling FEA calculations.
Resistance checks of welds and bolts.
Bolt bearing stress checks.
Punching shear checks.
Pull-out checks of anchor bolts.
Slip checks of slip-resistant bolt layouts.
Bearing surface checks.
Simplified resistance checks of members net sections.
Simplified resistance checks of cleats.
Block tearing checks.
FEA checks of single components, aggregates or whole joints, finite element models are automatically created and analyzed (linear, non linear, buckling).
User’s checks: user can add further formulae and C.S.E. automatically includes them in the checks.
How to learn C.S.E.:
Tooltips and context sensitive help.
