Re: Response Spectra

I am unsure as to exactly what you are asking, hijratun. DEEPSOIL is a site response program. Does DEEPSOIL also have spectral matching capabilities I am not aware of? In SeismoMatch, you define the response spectrum to which matching in the time domain, using wavelets, is performed. Could you clari...

Scale Factor

The program appears to ignore the specified scale factor in Step 3. Regardless of the specified scale factor, the matching appears to be performed to the specified target spectrum, not the specified target multiplied by the scale factor. The scale factors specified in the Settings appears to be igno...

Re: How to define a shear joint (hinge)

A link-type element between two initially coincident nodes with the proper degree-of-freedom parameters set to your desired shear strength and stiffness should work. See the excellent details in the help system for more information. It is always best to use the latest version as well. Best of luck i...

Re: Damping

The software does not have this capability, but it is a fairly simple hand calculation. Use the "logarithmc decrement" method, which may be found in most any textbook on structural dynamics, or from a web search on the term.

Re: Static Pushover analysis on a Bridge Model.

What element type are you using - DB (displacement-based) or FB (force-based)? If DB, you may need to subdivide elements. Just a thought. Also double-check units.

Re: link element

The models may now be downloaded directly from the Sample Models section at the SeismoSoft website.

Re: Time-Step Change

Increasing the time step will actually omit some of the data. Decreasing the time step will increase the resolution by linear interpolation between original points. When you multiplied the time step by 4 you actually omitted a large section of the data. That is why it changed. You can load an accele...

Re: Pounding Effect

A forum search on the term 'pounding' will give quite a few hits and should get you on your way.

Re: Base Isolator

There are some models of isolated structures on the SeismoStruct support page found here: https://seismosoft.com/seismobuild-seismostruct-sample-models/ Isolators in these models have been treated as link-type elements using, for example, the bi-linear kinetic, link element. See the User's Manual fo...

Re: Seismomatch- Matching of Time History

First, this is not unusual. A pioneer of spectral matching has been quoted as saying that 80% of the records generated through such processes should be discarded. This does not mean it is not a valuable tool. It just means you have to put a good deal of work into doing it correctly. Your period rang...
