    Dear Sir,

    Can you please provide the list of major changes in new version 426 from 399.

    The results have significant variation from previous version specifically for...

  2. Compile and link environment any documentation?

    Closed | Responses: 1

    Compiling and linking this source code is by no means straightforward. I have been able to successfully compile and execute many samples of code in Qt and Qwt environments, even the gsl and...

  3. Crash with version 3.99

    Closed | Responses: 1

    Albert and/or Ellen:

    I downloaded version 3.99 and it is crashing when I try to show the FAS Data or RS data for source theory input.  The error message...

  4. Why Strata crashes after copying a Response Spectrum within RVT approach?

    Closed | Responses: 0

    I want to compare equivalent linear results with RVT method for a case where I do not count with bedrock time histories. To approximate ground measurements, I would like to back calculate the...

  5. Implementing batch mode

    Closed | Responses: 3

    Dear Dr. Kottke,

    I'm currently working on adding 2 features to the strata application.

    1st: Human Readable file format (this is done using the boost library, and...

  6. Is ti possible to call strata from the command line?

    Closed | Responses: 1


    I would like to launch a series of strata calculations through a script. The question is if it is possible to launch strata from the command line and/or control some type of text...

  7. Baseline Correction for Shear Stress/Strain Time Histories?

    Closed | Responses: 1

    In the Time Series Output Specification tab, shear stress and shear strain time histories have an option for baseline correction. The manual seems to indicate that baseline corrections are only...

  10. Problem with deconvolution

    Closed | Responses: 1


    I have been trying to deconvolve my seismic data, but it isn’t working properly. I have this soil profile:

    Thickness 2.00 m // 6.00 m // 15.00 m // Half-Space Bedrock Vs ...

  11. Drift in raw output & baseline correction

    Closed | Responses: 1

    Hi there,

    I am finding the output from Strata has significant drift in the displacement time history – and even when baseline correction is selected the final time history...

  12. Where are saved non-linear curves ?

    Closed | Responses: 1

    Dear Albert,

    According to the manual, p. 49, non-linear curves entered in the NonLinear Propery...

    Hello, I would like to ask what is the bug of strata and when is it going to be released?

  14. Constant modulus

    Closed | Responses: 1

    What is the best way to implement a constant shear modulus (say 1.0 linear behavior) in STRATA? I tried a custom GGmax model in the “soil types” tab with a single row containing...

  15. Unlocking the input file.

    Open | Responses: 1

    I tried to deconvolve a recorded motion at the surface to get the within bedrock motion. I selected the only output to be acceleration time history of the bedrock (within or outcrop). As soon I...

  16. strata with velocity inversion

    Closed | Responses: 1

    My name is Gaetano, and i have a question about the velocity inversion which take place at the conglomerates-clay interface; this is my velocity profile: thickness (m) – vs (m/sec) 4 ...

  17. Why the number of points is limited by stop line=99?

    Closed | Responses: 2

    Hi, my name is Michelangelo and i have a question: why in the “Motion (s)” section the number of points is limited by stop line = 99?


  18. Auto-discretization in Strata: does it work correctly?

    Closed | Responses: 1

    Dear developers,

    We have experimented with Strata to determine the transfer function at a site in Belgium using equivalent-linear modeling. We have compared the result with two similar...
