    Slopes and probability of failure

    This thread has been inspired by the practical issues posed in this other thread: https://www.eng-tips.com/viewthread.cfm?qid=493211 The issue was basically that Pf, or Pof = Probability of failure, sometimes, or often, seems to be high in relation to the FS, the minimum Factor of safety of the...

    Updates from Italy

    Hi all, just a few updates here. Now my main business is as a caregiver for my autistic son. I've taken him back home to see if improvements are possible. I've been studying psychopharmacology rather than geotechnical matters. Life is pretty hard and improvements are not significant. I'll be...

    News from Italy

    Hi all, I'm very ashamed I did not visit the forum and did not answer previous enquiries, I'm going to make up for it. Thanks BigH for sending me the recent email packed with great pictures and the Jazz appreciation piece. I'm still thriving, although at times very busy, I have to run now but...

    Still alive and well

    Hi everyone, I'm still alive, although I've been absent for a while. After I retrofitted my house, in 2016, things kind of started heading some weird ways. Now they are better off, I'm still working in Italy, often involved in small construction projects, sure not huge dams in exotic locations...

    Slab on grade on expansive-shrinking clays

    Hi all, I may be involved in a project of a pretty large industrial building. An issue which I'm not familiar with is going to be design of base/subbase and improvement of subgrade, which is several meters of clayey soil which shrinks and expands with variations in moisture. Basic practical...

    Advise on foundations and geotechnical Journals

    Hi all, I'm just starting to recover from all the work related to retrofitting of my house, not over yet but definitely over the hump. I'm feeling the need to catch up on thechnical literature. I know it has been already discussed, but it was years ago maybe. Fields: geotechnical engineering...

    Merry Xmas!!!

    Merry Xmas to all, no snow at all here in Italy, no rain, just Sunshine, fog in some areas and above the average temps. Some vacation time is dedicated to finish up tedious accountancy and admin work. The other to eat and drink and binge! Ah ah, I wish it! In middle age, I cannot escape the bad...

    Update

    Dear friends, I've being living a nearly frenzied life for a while now. Started a major retrofitting project of my house in August, then had to empty the building and move out last month and rent a flat, to return when the works are over. I had to supervise personally all the project stages...

    Berezantev et al. article

    Anyone can share the following original article or has indications on where to find it in the web? Berezantzev, V. G., Khristoforov, V. S. and Golubkov, V. N. (1961) ‘Load Bearing Capacity and Deformation of Piled Foundation’, Proceedings 5 th International Conference SMFE, Paris, Vol. 2...

    Charlie Mingus, Don Pullen and the devil

    Devil's blues is a peculiar performance from the Mingus quintet. Mingus starts off with a bass solo George Adams keeps on with a weird vocal performance. Let's say his voice is not the most harmonious in the jazz scene. But singing the devil's blues it's OK, he really sounds possessed... What...

    Piano and seismic waves

    Jason Moran is a recognized Genius of jazz piano (he received a McArthur 0.5 M$ fellowship). In this video, he plays his composition 'Antipode Blues', related to the seismic waves radiated from an earthquake and reaching the antipodes. At the end we can listen to his rendition of the clash of...

    Stepwise plots

    Dear all, My issue is interval or stepwise plots similar to those in the portrayed illustration (soil parameters versus depth). I could not find a direct way to plot them so I had to use an IF statement. The IF statement I used has also a problem that is, if the value is not the same for at...

    Again on static+dynamic modulus reduction

    thread1134-353433 Pls see the above thread for reference. I wrote to Paul Mayne but maybe I was not very much clear on the subject, since he suggested to me a couple of interesting articles by Bolton and Others, putting static reduction and dynamic degradation in the same conceptual framework...

    Critical state soil mechanics

    I'm posting this after reading BigH in one of the open sections. Which aspects of CSSM can we put in practice in the routine getoechnical design? I have some difficulties in studying a topic if I cannot link it to some practical purpose. I believe we have already discussed phics and Sucs, but...

    L'Aquila quake: experts cleared in appeal but one

    The Appeal Court in L'Aquila reversed the first degree sentence which found 7 experts guilty of manslaughter for distorting the public perception of risk and causing the demise of some Citizens. The appeal judges could not find a clear causal link between the meeting of the advisory panel and...

    Site response handbook

    Guys, I'm just over with writing a practical handbook on seismic site response. That's currently in the Italian Language only, for now, I wonder if I should insist and have the publisher translate it. As far as I know, that's the only practical handbook in the world, dealing with 1D, linear...

    Depth of influence for settlements

    This is something which is really not too clear. The condition is the one where a rigid layer is not found near surface. In some textbooks, the depth of influence for calculating settlements ZI is assumed to be the one where the load surcharge drops to 0.1 times the value of overburden...

    Charts with >254 data series

    Hi all, my goal would be to paste numbers from a data table produced by another standalone software. I'd like to plot a chart with at least 1000 columns (data series) and 128 rows. As far as I've seen and read, Excel can't do that, being limited to 254, or 255 data columns. Is there a way around...

    Site-specific seismic response analysis

    Hi all, I'm diving deep now into site specific seismic response analysis, those analyses where surface ground motions are figured out by algorithms which determine the amplification of the bedrock motion. Do you guys kno wabout any specific regulations or parts thereof aside the very few ones...
