Re: error in eigen value analysis
Has this been determined to be a bug? I am having the same issue, and my nodes are coincidental. Only when trying to do an eigenvalue analysis does this occur.

Complex Model Convergance
Hello, I have a very complex model, with links/joints modelled at every connection in the building, and I am having issues getting it to converge. I have read most of the forms on convergence issues, as well as the seismosoft guide on convergence and tried applying these concepts, but it did not wor...

Re: RC JOINTS- Shear panel modelling
Can you provide any references or citations that confirm that theory please?

Re: RC JOINTS- Shear panel modelling
In the Yu dissertation, there are 3 important things that were considered in the joint model: 1) Bar slip springs 2) interface shear spring 3) shear panel rotational spring All the parameters were provided as well. The models provided by seismostruct only accounted for the first 2, and I need to kno...

Re: RC JOINTS- Shear panel modelling
This does not answer my question. I have gone through the link elements of these models very carefully, and while bar slip spring and interface shear spring were modelled, the shear panel interface was not included in your models and I am wondering why. Considering this was one of the verification f...

RC JOINTS- Shear panel modelling
I have been extensively studying the RC Joints (example 1) verification files (Ch4 joint 1,2,3) regarding the modelling of RC joints as I intend to model other RC joints. I have read the seismostruct verification document and the original dissertation by Yu regarding the joints to see how the parame...

Re: Hysteresis graphs
So you suggest if I change the rotational response properties, I may get a lower peak?
Also I have set the plastic hinge at 50%, because the calculated PH ( originally 15%, and 10%)was causing higher peaks.

Re: Hysteresis graphs
I've ruled out these factors " material strengths, modelling of confinement, modelling of shear failures,"
Modelling of second order effects is done automatically if I've ticked that box, isn't it? I am also using FBPH, so that should not be causing it.

Hysteresis graphs
Hello,
I am doing some hysteresis verification of my own, and I notice that a constant problem is the peak forces don't match up with experimental results. The software always produces higher peaks. What could be causing that?
