modeling of buckling restrained braces in a Rc moment frame

[saharnaz]

Hi
my model is a 6 story 2 bay Rc moment frame that i've used buckling restrained knee braces in it,but the pushover analysis dose not converge?
what should i do?
has anyone done this before?

Hi saharnaz
To repkly your question, first I should know some points:
Did you use fiber sections in RC frame? what kind element did you use for modeling buckling restrained knee braces?

[saharnaz]

Hi
yes i use fiber section.for yeilding part of brb,truss element.and for the rest of brb,elastic beam column.

if you use test "NormDispIncr" , increase number of iteration.
