how to model rotational spring at joint

Post by izzettin »

my question is how to model a rotational spring at joint center (the intersection of beam and column elements) with rigid offset?

while zerolength element requires two nodes as input arguments,
for exterior joint there are 5 nodes and for interior there are 6 nodes

how to connect the zerolength elements to those nodes and,
what are the nodes and corresponding dof to be fixed?
