I want to design a building with BRB. for modeling BRB in it I have two kinds of sections ("core brace" and "star seismic") when I use "star seismic" and define "Area of yielding core", after design, I found that the area that used, is about 4 times bigger than that I define. Do you have any idea about this problem?

and

for defining inelastic data for BRB, in the picture that I send, I do not know how should I fill it? and what does this parameter means?

thank you for your help
