CEEN 545 - Lecture 22 - Introduction to Soil Structure Interaction

This brief lecture introduces you to the topic of soil structure interaction. A description of the basic phenomenon is given, and general guidance is provided as to when SSI could be beneficial in a structural response analysis. The idea of kinematic and inertial analysis is introduced.

This is pure gold, thanks for sharing the information!

[@sterlingwallstrum8975]

Great overview, and good tip on OpenSees!

[@MRDS12]

It’s one of the best video on Soil-structure interaction I have ever watched. I have read about 6-7 research paper on the topic. But, I have to admit, this video provided me with much more knowledge. Thank you so much!

[@konanblejustin855]

Sir, after seeing this video, i wanna know more about SSI. So can you please give more precision about the Kramer book.? I can not find it.

[@abinashmandal6202]

Its Geotechnical earthquake engineering by Steven Kramer and is available online.

[@Emma_Junaid_Claire]

Sir, I'm doing my master in Structural engineering and now I wanna take research on this topic. Can you please give me some good helping material related to SSI coz this stuff is new for me.

great video. I have always wondered about this magic number that determines the characteristics of the spring replacing the ground. Because replacing a multilayer nonlinear soil with a single digit is, in my opinion, quite breakneck :). for engineering purposes it seems to me that a simplified model could be built. because for buildings, total settlement is of secondary importance. if all the foundations are lowered evenly it is not a big risk. however, it is important to determine the differences in the settlement of the foundations or the angle of rotation for a single foundation. a useful procedure would be to replace the soil with columns whose deformation would be the same as for the soil. length of these columns to meet the standard conditions. while the stiffness of the column would increase with the depth and it could be determined, for example, on the basis of the oedometric modulus. a reliable procedure for calculating such substitutes is needed. I am asking someone with the appropriate qualifications for help, I can also offer mine.

Great and clear introduction to the SSI. Perhaps the SSSR ( soil-to-structure-ratio ) could help to determine when to use a SSI analysis. SSSR = h/(Vs*T). When SSSR > 0.1 perform SSI is very advisible, otherwise not.

Sir its so Awesome love uou

[@DanuwatMaoleethong]

very useful

[@maanzafar]

I could easily make out whats SSI is all about. Thank you!

which version of SAP2000 would you recommend for i7 8th gen and 8gb ram ? for soil structure interaction ,

[@arigato792]

Super video. From a structural engineering point of view, there are no "soft" structures. In fact, I have never heard of the term. Soft story, sure, but that doesn't apply here. Here we would call them flexible structures since you mention stiff structures, in the same breath. An interpretation from a structural point of view for kinematic interaction would be the compatibility, or "displacement interaction", while inertial interaction would refer to "force interaction". If we cant solve our forces, we start looking at displacements. Ive probably watched this video 3 times. Love it.

[@HardikSolankiMJA]

Please Share Some material about SSI.. I want to learn in detail

[@premnathselvarajah1639]

Really appriciate it.Very clear introduction, I am ready to read more now. Thankyou Prof.Kevin.

[@steffiilloza3432]

Great lecture and very nice explanation, Thank you Professor

[@annabellewah5017]

the best explanation I have ever watched! thank you for sharing!!!

[@PURNAMILIND]

Million thanks sir.

[@dkir3829]

Thanks for the lecture, it is useful to get an idea of ssi

[@jorgemendoza3500]

Great material for introduction.

[@sahiljan11]

i got a lot of help. nice work

[@jamilasyria3122]

I am registering for opensess but they ask for middle number, what is the right answer to complete "You have provided an invalid answer to the question." and the quenstion is What is the middle number?: * 1 2 3

[@hamzamMR]

great lecture, i would liked if we can get references for SSI. thank you Professeur

[@radiatouati5731]

Hi, I am interested in this topic and I want more references about it, can you help me or give me a way to contact you.
