Modeling of Friction Pendulum in Seismobuild Advanced

[StruttureSpeciali]

SeismoBuild ADV nominally offers the ability to model Friction Pendulum isolators. In my experience, however, the parameters that can be entered in the modeling window, derived directly from the one for elastomeric isolators, do not allow for correct modeling. It would be preferable for this window to be adapted to the actual characteristics of FP isolators, and not forced to show modeling capabilities that are not actually available. Seismosoft on the other hand does not provide adequate tutorials for the correct modeling of FP isolators. The final result is a pair of SW that promises more than they actually offer.

Can you be more specific? What do you mean with "the parameters (of the Friction Pendulum isolators) that can be entered in the modeling window, are derived directly from the one for elastomeric isolators"?
If you mean that the two types of isolators have the same input, this is not correct. The parameters requested for the curved surface sliders, the elastomeric and lead rubber isolators are different. Furthermore, they adapted to the needs of each type of isolator for easy and efficient modelling.

Maybe some of the sample models available at Seismosoft would be of help as a tutorial. There are models which illustrate the correct specification of isolators modeled as link-type elements in:

Single Bridge Bent with an Isolated Mass
7-Span Bridge
7-Span Bridge No. 2
Model with isolators

These sample models and many others are here:

Best of luck and I hope it helps.
