pinned connection

Post by prestige » 21 Jan 2019, 12:22

hi , i need to define the pinned connection(beam to column connection & brace connection). i use link element (linear sys) for define pin connection ,is it true?
what kind of curve behavior must be use?(linear sys?)
for pin connection the stiffness ( m1,m2,m3 )must be close to zero?
please help me

There are options which can be simpler than defining a link. It depends on the intent of your model and the behavior of the element in question.

For braces, axial load is often the only consideration and the inelastic truss element might prove useful. For beams, specifying moment releases in the element connectivity dialog might do the trick.

I hope this helps. Best of luck with your Seismo-models, prestige.

tanks
for infrmFB (beams cant be moment releases without link element---pin--- if dont do this ,will be converge problem )
and for braces the connection must be define with pin element (because braces must be buckling) if use truss element for braces we cant see any buckling( this model like BRB)
