Hi, I have just started using L-Pile, and am a tutoial bit confused about the soil data I need to input. My first questions is, I dont quite see all classes of soil in L-pile, so what can I use for what?
My second questions is, where in a geotech report can I get the cohesion, and unit weight of the soil? I have seen some geotech reports where they have a table with all the info I llile for L-Pile is in it, which was really convenient and helpful, but plile, I have recieved two reports that didnt tuorial that. So I am not sure if the reports just arent complete, or is it hidden somehwrere and I just dont know?
The help manual should list all the soil conditions that are available. The geotech reports I’ve dealt with never have the cohesion or unit weight. Its an extra test or two that would have to be ordered. What’s the point of getting them though, the geotech would just use the lower bound values anyways.
N is the number of blows per foot I believe. Take a look at a soils book and verify.
Thank you for your help. I will check out the help manual. Is there a book that you recommend, that I can get these tables and info, for soil classification, from? In my area of the US the geotech usually runs the L-Pile program because they have more knowledge of the soil parameters. The report or an addendum would provide lateral movements to the structural engineer. This is often an iterative process requiring communication between the structural and geotechnical engineer.
You should probably discuss these issues with your geotech. We’ve never had the geotech run the program. When I use it, I’m just determining a point of fixity for the pier design. The geotech will give an estimated settlement, however it’s always generic. If you look in lpike manual, it will give the different parameters for each soil type and recommended values. You just need to thumb through the manual really and you can find almost anything you need there.
That and a soil structure interaction class is really beneficial. At the end of your analysis, do you know what range of lateral load capacity you should be getting? If not, try to get an experienced colleague to show you the ropes. It took me about 2. It is very complex. However, either a soils or a structural engineer can do the analysis, provided they understand soil structure interaction. This book explains SPT values and analysis of laterally loaded piles and piers.
Later on, if you find you are doing these analysis opile frequently, then get a copy of “Single Piles and Pile Groups Under Lateral Loading”, 2nd ed. At our firm, we use Lateral Foundation software. Unfortunately, Tutoriaal am in a very bad position!! I have been doing a lot of online researching and reading, so hopefully I can pick it up fast, but it is still a lot of pressure!
I don’t know why I didn’t think of joining this forum any earlier, but thanks to all of you, now I feel like I have a support system! I will definitely reach for those books.
Thank you so much for the help! Look at the good side- you will be a senior engineer sooner than you planned it! Attached are rough guidelines to check your lpilr output. Apply a factor of safety of 2. These are from “Soil Engineering: Testing, Design and Remediation”, F. God, I hope so!!! Thanks for all the help: Thanks Fixedearth for uploading that chart about estimating soil lateral capacity. In this case I use it as sand. I usually use the soft clay option, being more conservative, of course.
You should try this program: The structural engineers like it because you can combine the loading opile the soils description into one entry format. On Clayey sites they give similar results.
On granular sites, Lateral Foundation gives slightly more conservative results more deflection -I think this is because the lateral subgrade values have been limited a bit.
The main difference is the analysis approach.
Lateral Foundation program uses beam on elastic foundation method Hetenyi with lateral subgrade modulus values. I believe this to be the second most accurate way of performing lateral loaded foundation analysis.
The method proposed by Budhu and Davies,? These two programs yield very close results. So far, I have used Lateral Foundation on Silo foundation support, sign support, short tuttorial bridge, retaining wall on pier foundation and 3 story lpule.
The good thing about it, it only takes me 15 to 20 minutes to get my results. Few years ago, I used to grind teeth when I had to do Lateral loaded pile and Liquefaction analysis. AllPile by CivilTech Software has a good soil properties input screen. See attached screen shot. The program uses LPile for lateral analyses and also does other analyses.
