Model beam continuity

[jocagalhao2000]

Hello all,

Do you know how can I model bema continuity over a pinned support....
The beam bending moment doesn't go to the supports (there's an hinge)
and continuous to the other side of the beam...
Simple but with *BOUNDARY, NODE, 1 , 3 or NODE, PINNED I get a hinge
on the beam, and i want an hinge on the support....

Thanks!

The solution is to use a MPC between the dofs of coincident nodes at
hinge for example. The kinematic coupling may work ?

If I understand the problem correctly, this kind of thing is usually
done by defining a beam end release, whereby you specify that end 1 or
end 2 of a beam element does not transfer force or moment for a specific
degree of freedom. The beauty of this is, it is relative to the beam
coordinate system. For example, if you release "T", it means the beam
cannot transfer torsion, i.e. moment about its own x-axis, regardless of
how the element is oriented in space. Look up "Element end release" in
the Analysis User's Manual (section 28.5.1 in v6.6).

other option could be to use appropriate connector element. Use node to
ground connectors. May be a cartesian with all 1,2,3 CORM defined with
rigid elasticity.
