Parameter definition
Variable | Description |
---|---|
coid | Command ID |
entype${}_r$ | Rebar entity type |
enid${}_r$ | Rebar entity identification number |
entype${}_c$ | Concrete entity type |
enid${}_c$ | Concrete entity identification number |
keep | Remove from or keep decoupled rebar elements in model |
Description
By default rebar elements (ELEMENT_REBAR or COMPONENT_REBAR) are automatically tied to any solid element in the underlying mesh (where they are embedded). In addition, rebar elements that are not embedded in the solid mesh stay active (but unconnected).
This command is used to limit the rebar coupling to a user defined list of parts. Uncoupled rebars can removed from the model.
Example
Rebar cage trimming
A rebar cage is embedded in a circular concrete slab. COUPLING_REBAR is here used to trim (delete) rebar elements outside the slab.
