Thanks dear seismosoft
geometrical non-linearities is active.
i think the the vertical/gravity loads of the structure is correct.
you think that max drift of a steel moment frame how much can be??

<t>Thanks dear huffte.<br/>
with this value (ultimate strain = 0.2) my steel moment frame have unreasonable and large drifts (displacements) and my frame still show resistance.(by increasing base shear!!)<br/>
and i cant find collapse point(lateral dynamic instability) <br/>
the place dynamic ...

Thanks seismosoft & huffte
I am so dizzy for this parameters!!!!
can you help me to find true value of fracture strain and strain hardening paramete??
evrytime i reach to the different RESOLVENT!!!

I attempting to estimate the max drift of a steel structure during strong ground shakin.
and with this value i reach to the wrong and huge displacement.
even 2m in 1 story frame!!!
i think my ultimate strain is wrong for this work.

<t>Hello<br/>
I have steel frame with ASTM A992 material.<br/>
my strain in fracture Eult is 0.2.( is it correct??)<br/>
i put this value in the Esp=(fult-fy)/(Eult-fy/Es), and my Strain hardening parameter is 0.0026.<br/>
so is not in the ranges from 0.005 to 0.015. <br/>
what is the problem???<br ...

Hi
can we predict(determine) the collapse point with decreasing of Base Shear??
I have steel moment frame and they reach huge displacement. [V]
mention resourse please.

Hi everybody
For The perform IDA analysis of 2D SMF Steel Frame which one of the Beam Column Elment Types you propose to me??FB?DB?FBPH?
and in FBPH method How can i compute the plastic hinge length(Lp/L) in steel column?
Thanks
