Validation Resources on Soil-Structure Interaction in RFEM6

Dear Dlubal Support Team,/ Technical Support

I hope this message finds you well. My name is Sachin, and I am currently pursuing my Master of Engineering. As part of my dissertation, I am working on IDA-based Seismic Fragility Assessment of RC Frame Buildings using Soil-Structure Interaction (SSI) effects.

For my research, I am conducting nonlinear time history analyses of RC frame buildings on soil within RFEM 6. To ensure the accuracy and credibility of my work, I urgently require validation resources. Specifically, I kindly request:

  1. Standard research papers or reference studies related to SSI modeling in RFEM.
  2. Example models or benchmark problems that demonstrate nonlinear time history analysis of buildings with soil-structure interaction. That Model or Benchmarch I Showed Against External Viva Sir or Experts.

This validation is compulsory for my viva/final examination, as I must show proof that my work has been verified against established studies or models in RFEM 6. My dissertation deadline is approaching in one month, and I sincerely request your guidance and support in providing any available references, models, or documentation that can help me validate my analysis.

I bow my hands in request and truly appreciate your assistance in helping me complete this important academic milestone.

With respectful regards, Sachin Master of Engineering (Structural Engineering)

Ahmedabad, India

Hi Karen,

thank you for inestigating SSI interactions with our Nonlinear Time History Analysis.

The Analysis type was released just in the end of last year and several interactions have not been verified against external resources. Currently we cannot deliver the desired comparisons and the topic is not tested yet from our side. For such cases, a warning for Unsupported Features is given within the program.

Please feel free to validate the results against literature by yourself. The unsupported warning does only hint out, that it is not yet tested and investigated on its plausability from our side.

Best regards

Can i Validate Geotechincal Analysis For Soil Structure Interaction .. All Webinar of SSI model that Any one of model Published in Research paper that i want . Please Help.. If SSI interactions with our Nonlinear Time History Analysis Not Available Atleast I Validate Geotechnical Analysis

Sir Can You Reply

Hi Karen,

Validating such a broad field as SSI in its entirety is difficult. However, the underlying scientific work that has been implemented in our program is listed in the theoretical principles. This applies, for example, to the 2D-constrained-modulus method, especially in soil-structure interaction. The material models are named and described and correspond to the behavior described in the literature.

We have also made several contributions to the validation of sub-areas. These range from nonlinear material behavior (KB 1976), up to pile load-bearing behavior (Webinar) and complex ground failure states using the Phi-C reduction method (KB 2030) compared with literature references.

In any case, your work sounds extremely interesting, and I wish you every success. If you wish, you can also submit your thesis to us after completion and receive great benefits:

Sir I want to validation from any standards research paper from above videos reference ... Above Video Links Model Proof that can i validate

Thank you for providing these webinar links! If literature is referenced in the videos, it should be listed in the additional materials at the end. If no literature is listed, these are examples created by our engineers for demonstration purposes.

Ok Thanks A Lot.. Sir That (examples created by our engineers for demonstration purposes) can i Validate That ?.. From Your Side Any Proof For That..

Sir if Literature Not Available I want to Validate Model in Webinar / Demostration Model ... Any Proof Made By Your Side For my External Viva Exam sir.. I will Watch Webinar and Make same Model from video and i will validate it but for Proof of validate from Your side is much need or Good / Benefical..

Most webinar models are available for download. You can find them by scrolling down and clicking on “Models to Download”. Also you can find in this section more related information.

OK Sir Thank You So Much for Your Reply / Or Time...
