thanks for the answer

and is this the plastic hinge length (Lp/L)for one side of Member or sum(total) of two side of my member???

Hi
I have modeled a steel moment frame with Inelastic plastic hinge frame element - infrmFBPH and bilinear steel model.
Unfortunately i cant Compute the plastic hinge length [V][V]
can you help me to compute plastic hinge length for W18x50 section with fy=50ksi and L=25ft??[?]

Hi
I have 2 questions.
can i recognize the collapse point with max drift Va max Base shear curve???
I want plot IDA curve and i have to determine collapse point[?]

Thanks Dear seismosoft.[:)][:D]

Hi
Do you know anybody ultimate or maximum strain of the ASTM A992 material??[:I]

Hello everyone
I Have Steel Frame with A992 Material(USA Steel Material).
Fy = 50(ksi,in)
Fu = 65(ksi,in)
How can i get Strain hardening parameter and Fracture/buckling strain in Bilinear steel model and also correct sample plot?[:I]

<t>Hi my friends<br/>
in my research, I need to perform IDA, but i have a problem with IDA curves. because of increasing of the slope of these curve[ Sa(T)----spectral acceleration in fundamental period Vs Drift max] i can't recognize the dynamic instability on these curve. probably, you know that ...

yes slope. sorry
he is my friend and working on same project.

Hi
i have steel 2D Frame. How can i get maximum story drift ratio of each Story in IDA method. i need Incremental dynamic analysis response plot of spectral acceleration versus maximum story drift ratio.
