Connections with composite sections
As well as allowing you to design connections between different simple sections (either laminated, shaped, reinforced or timber), the program allows you to design and analyse connections with composite sections made up of several sections.
Unlike the definition using several simple bars, composite sections allow the program to work with a single set of forces for the entire bar.
The sections implemented are as follows:
Rolled steel I section:
- Double in box generic joint
- Double welded in box
Rolled steel channel section:
- Double in box generic joint
- Double welded in box
- Double in I generic joint
- Double welded in I
Rolled steel angle section:
- Double in box generic joint
- Double welded in box
- Double in T generic joint
- Double welded in T
- Double in U generic joint
- Four in box generic joint
- Four in cross generic joint
- Four in I generic joint
Cold formed steel channel section:
- Double in box generic joint
- Double welded in box
- Double in I generic joint
- Double welded in I
Rigidi section of shaped steel channel:
- Double in box generic joint
- Double welded in box
- Double in I generic joint
- Double welded in I
Formed steel angle section:
- Double in T generic joint
- Double in cross generic joint
Rigid angular section made of shaped steel:
- Double in cross generic joint
Rectangular hollow section:
- Double with generic joint
- Four with generic joint
Circular hollow section:
- Double with generic joint
- Four with generic joint
During the design of the connection, each part of the bar will be identified. To model the application of loads at the ends of composite bars, the same procedure is followed as for simple bars.
With regard to the analytical model, the end nodes of all sections comprising the bar shall be connected by means of fictitious rigid elements to the fictitious load application node (located at the centre of gravity of the composite section).
