Abaqus
provides a library of basic, assembled, and complex connections.
The connection-type library contains:
translational basic connection components, which affect translational
degrees of freedom at both nodes and may affect rotational degrees of freedom
at the first node or at both nodes on the connector element;
rotational basic connection components, which affect only rotational
degrees of freedom at both nodes on the connector element;
specialized rotational basic connection components, which in addition
to rotational degrees of freedom affect other degrees of freedom at the nodes
on the connector element;
assembled connections, which are predefined combinations of
translational and rotational or translational and specialized rotational basic
connection components; and
complex connections, which affect a combination of degrees of freedom
at the nodes on the connector element and cannot be combined with any other
connection component.
