Re: SSI1 - SHALLOW FOUNDATION MACRO-ELEMENT PROBLEM
I believe the reply from Seismosoft Support is helpful to solve your problem. To further clarify this and other issues related to the use of the new SSI macro-elements, a set of example problems is under preparation and will be posted as sample models with these link elements.

Re: Fully coupled stiffness, damping and mass matrices
<t>Dear colleague,<br/> <br/> From your question I gather that you are trying to use lumped parameter models (LPMs) to account for the frequency-dependence of foundation impedances in the linear elastic range. Unfortunately, the lumped elements in SeismoStruct (link, mass and dashpot elements) have ...

Re: Computing mass/length
Dear lacampos3,
The mass per length for that element, which represents a slab "slice" with 0.9m width and 0.1m height, was computed by multiplying the RC mass density of 2.55ton/m3 by the dimensions of the slab "slice".
Best regards,
Antonio

Re: geometric nonlinearities background document
<t>Dear asivals,<br/> <br/> I am the author of the conference paper you mentioned and I was the one who implemented such geometrically nonlinear formulation in SeismoStruct.<br/> <br/> I have some difficulty in understanding what you mean by "cheat", since the authors have absolutely no participatio...

Re: Dashpot
<t>Dear Bassking,<br/> <br/> By your description, something strange is happening indeed. If the same stiffness and different damping was being assumed in both cases, there should also be a phase difference between them... Unfortunately, I would need more information on your models in order to give y...

Re: Spring and dashpot
<t>Dear Bassking,<br/> <br/> There are two options for modelling a parallel spring+dashpot:<br/> <br/> 1. The one provided by huffte in the previous reply:<br/> - a common moving node for both the link and dashpot elements;<br/> - a fixed node for the other extremity of the link (the dashpot element...
