Dear user,
We have a special element for modeling spherical sliding bearing isolators (in fact friction pendulum isolators), which is the Bearing 2 element.
The bearing 2 model has coupled response between the horizontal axes and includes a coulomb velocity dependent friction law.
Did you use the ...

Dear user,
After receiving your model we ran various tests and discovered that a bug exists in the programm affecting the conversion of units for the initial stiffness variable for the Viscous damper curve. The bug will be corrected in the forthcoming Seismostruct version. Unitl then we suggest that ...

Dear user,
On many cases the damping result depends on the correct selection of the damper parameters. In order to help you I would like please to clarify with what units you are woking and to which degree did you change the value of C.
Also please verify the correct connection of the damper with ...

Dear crimaval,
Semi-active dampers are not available in Seismostruct. Thank you for your suggestion which we will take into consideration for future versions of the software.
Best regards

Hello,
I tried to install Seismostruct by double clicking on the installation executable but got a window with the installer icon writting 1158: and the Ok button. After pressing ok the installation stopped.
Could you provide any help on the above?
thank you

Hello Navid,
the amplitude units are same as the units of your time series (for example g, m/sec or whatever your units are) multiplied by seconds (the time interval unt). So in order to obtain the real amplitude for a specific frequency in your results you need to multiply the amplitude with 2 (due ...

Dear llem0,
It would help if you could provide us with more information.

Concerning the length of your time series, what is the length (in time series points) of the maximum time series you are interested in analyzing? Are you interested in analyzing the full 8 hours recording (some millions of ...

Dear User,
This is a known problem. In order to solve this issue please send a message to licensing@seismosoft.com through your academic email address providing a screenshot of the problem (screen with regstration fields and system not responding). You will then be provided with a registry key which ...

Dear User,
Thank you for your comment. Indeed in the IMK model a θu lower than θpc could be used to model complete loss of strength before the system reaches the residual branch (for example in the case of brittle failure of connections).
We will consider removing the limitation you referred to in ...
