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.

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

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...

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

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...

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...

Chapter 4, Example 2, of the Verification Report should be an excellent guide in modelling shear wall structures. It is found on Page 77 of the Report.

The following verification problems should be very useful in understanding the steps required for various forms of cyclic loading. Chapter 2, Example 11. 2D Frame Subjected to Earthquake Loading Chapter 2, Example 16. SDOF System Subjected to Harmonic Loading Chapter 4, RC Building Example 1. Nonlin...

Just to be clear and rule out the potential units issue: 1. When you define the time history curve, you specify a factor of 0.01 to get cm to m. 2. When you define the loading, you specify a factor of 1.0, since you converted the units in defining the curve. If these are true, I believe you are corr...

You can place a node in the exact center and connect it to the corners with rigid links. Depending on your intended model, you may have to use rigid links to more than the corners.
