It seems that you are trying to achieve spectrum matching over a big range of period in one pass. This shall destroy the nonstationary characteristics of accelerogram even if you get the match. You need to imperatively increase the range in multiple sweeps. In addition, you need to select a motion ...

Thank you for your interesting explanation. I would like to elaborate little.
I model a pier with a mass at top and zero material density. I use infirmFB and do not take geometric nonlinearity. In case (a) I take one element for entire pier and (b) 4 elements for pier.

For (a), area of moment ...

Dear Hamidi
To retain fling, you need not filter. You should use raw data only corrected for baseline. The unfiltered motion only reatain fling, i.e., permanent static displacement. i shall request you to read the paper of Boore and Bommer published in Soil Dynamics and Earthquake Engineering with ...

Dear friends
Let us assume a cantelever pier modeled as (a) a single element and (b) discretized in 4 elements. Mass is lumped at the top and the pier is subjected to base excitation. I would like to plot the overall hysteretic response of the pier.

We have two options: (i) Global response ...

In FB model, generally one element per member is OK. But I have some confusion on the following aspects. Please explain:

1. What may be the basis of selection of appropriate number of IPs over the members?

2. How many fibers one should consider for a section. Do you believe that a stable moment ...

We have modeled a pier in FB elements. Mander et al model for RC element with lumped mass atop is considered. To include P-Delta, we sub-divide the member into four elements. For verification, we perform dynamic analyses (earthquake acceleration history) once again without including geometric ...
