Re: error in running analysis

<t>This message is an indication that at some particular DOFs the stiffness is zero (e.g. a node when only truss elements are connected, hence there is no stiffness in the rotational DOFs). <br/> It is not necessarily wrong, but as Tim mentioned it might mean that the model is unstable. I suggest th...

Re: Simplified bilinear hysteresis

<t>Hi Amir,<br/> I would suggest that you carry out a Google search (both the web and Google Scholar) for the Otani model, there should be plenty of information and resources on it. <br/> Regarding the code, any indivudual with basic understanding of progtramming, should be able to read it and under...

Re: Range check error

Hi Fiona,
If you manage to identify the exact steps that lead to the range check error, please send them to us, so that we fix the possible bug.

Thank you,

Re: Range check error

<t>Fiona hi and thank you for the model. <br/> Can you be more specific with the problem that you face, i.e. describe the exact steps to derive the range check error? I opened the model that you sent me, but I managed to add and edit elements, without problems.<br/> <br/> Thanks again,<br/> Stelios ...

Re: Range check error

<r>There seems to be an error in the code, a range check error is not reasonable message. Can you please send me the problematic model (or at <EMAIL email="support@seismosoft.com">support@seismosoft.com</EMAIL>), so that we can have a look? <br/> Thank you in advance.<br/> <br/> Stelios Antoniou<br/...

Re: modelling repair braces

Yes, at the first step of the incremental (pushover) analysis no incremental loading is applied yet, and the qequilibrated state reflects the initial (i.e. gravity) loading

Re: Simplified bilinear hysteresis

The takeda curve was initially developed for the hystereitc curve of R/C elements. It is mainly up to you and your supervisor to decide if the curve is suitable for the structural configuration of your steel model.

Re: Academic License Limitation

The only limitation is that it has to be used for academic and not commercial purposes, and that it is referenced appropriately.
There is no time or usage limitation, though.

Re: license of seismosignal

Zahra,
For an academic license, use the initial screen to ask for one (a valid academic email address is required). For a commercial license use the e-shop on the website to buy one.
