L-Pile Input Data – Foundation engineering – Eng-Tips

Later on, if you find you are doing these analysis more frequently, then get a lpi,e of “Single Piles and Pile Groups Under Lateral Loading”, 2nd ed. Depending on boundary conditions, pile-head loading may consist of a lateral load, a bending moment, a specific lateral displacement, or a specific pile-head rotation. Reasons such as off-topic, duplicates, flames, illegal, vulgar, or students posting their homework.

Thanks Fixedearth for uploading that chart about estimating soil lateral capacity. Posting Guidelines Promoting, selling, recruiting, coursework and thesis posting is forbidden. Thank you so much for the help! It is very complex.

I usually use the soft clay option, being more conservative, of course. The report or an addendum would provide lateral movements to the structural engineer. If not, try to get an experienced colleague to show you the ropes.


The good thing about it, it only takes me 15 to 20 minutes to get my results. FORUM8 will distribute them.

You should probably discuss these issues with your geotech. That and a soil structure interaction class is really beneficial. The piles may be installed vertically or on a batter and their heads may be fixed, pinned, or elastically restrained by the pile cap. Soil-resistance p-y curves can be internally generated by the program for the following soils: So far, I have used Lateral Foundation on Silo foundation support, sign support, short span bridge, retaining wall on pier foundation and 3 story residence.

My second questions is, where in a geotech report can I get the cohesion, and unit weight of the soil? It took me about 2. This is often an iterative process requiring communication between the structural and geotechnical engineer. Students Click Here Join Us! Thank you for your help. Register now while it’s still free! LPILE Plus is a manuap program based on rational procedures for analyzing a pile under lateral loading. The user may optionally ask the program to generate and take into account nonlinear values of flexural stiffness EI.

The Eng-Tips staff will check this out and take appropriate action. Resources Digital Transformation may be defined in a number of different ways by analysts or enterprise software vendors. Join your peers on the Internet’s largest technical engineering professional community.

My first questions is, I dont quite see all classes of soil in L-pile, so what can I use for what? On Clayey sites they give similar results. Product overview is as following.


User-defined multipliers are provided to increase or reduce the soil mahual p-y curves at any points along the length of the pile. See attached screen shot.

What’s the point of getting them though, the geotech would just use the lower bound values anyways. Values are helpful as nonlinear foundation models in superstructure analysis. Users may optionally input their lpilee soil-resistance p-y curves for certain soil depths. God, I hope so!!! Few years ago, I used to grind teeth when I had to do Lateral loaded pile and Liquefaction analysis.

Its an extra test or two that would have to be ordered. Download Now White Paper: N is the number of blows per foot I believe. This book explains SPT values and analysis of laterally loaded piles and piers. A Program for the Analysis of Pile in a Group GROUP has been well accepted as a valuable design tool for analyzing the behavior of pile in a group subjected to both axial and lateral loadings.
