Thank you for helping keep Eng-Tips Forums free from inappropriate posts.

L-Pile Input Data At the end of your analysis, do you know what range lplle lateral load capacity you should be getting? What’s the point of getting them though, the geotech would just use the lower bound values anyways. It is very complex. Posting Guidelines Promoting, selling, recruiting, coursework and thesis posting is forbidden.

Attached are rough guidelines to check your final output. The structural engineers like it because you can combine the loading and the soils description into one entry format.

LPILE Plus 5.0 for Windows: Technical Manual

My first questions is, I dont quite see all classes of soil in L-pile, so what can I use for what? Resources Digital Transformation may be defined in a number of different ways by analysts or enterprise software vendors. Up to ten different load cases may be applied at the pile head in a single analytical run. Reasons such as off-topic, duplicates, flames, illegal, vulgar, or students posting their homework. At the end of your analysis, do you know what range of manuql load capacity you should be getting?

Hi, I have just started using L-Pile, and am a little bit confused about the soil data I need to input. I will check out the help manual. On Clayey sites they give similar results.

Register now while manua, still free! Download Now Defense manufacturing is all about project manufacturing and project accounting. The piles may be installed vertically or on a batter and their heads may be fixed, pinned, or elastically restrained by the pile cap. LPILE Plus has the capability to perform push-over analyses and can lpule the pile behavior after the development of plastic hinges yielding. The p-y curves may be printed at any depth for reviews or reference.


LPILE Plus has capabilities to compute the ultimate-moment capacity of a pile’s section and can provide design information for rebar arrangement. The user may thus observe the detailed behavioral measurements of any portion of the depth of each pile sub-group. So I am not sure if the reports just arent complete, or is it hidden somehwrere and I just dont know?

The pile-head forces and movements are introduced into equations that yield the behavior of the pile group in a grobal coordinate system. Several types of pile-head boundary conditions may be selected, and the properties of the pile can also vary as a function of depth. L-Pile Input Data Thank you for your help.

The report or an addendum would provide lateral movements to the structural engineer. N is the number of blows per foot I believe. L-Pile Input Data We’ve never had the geotech run the program.

Unfortunately, I am in a very bad position!! 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! These are from “Soil Engineering: Several pile lengths may be automatically checked by the program in order to help the user produce a design with an optimum pile penetration.

L-Pile Input Data The help manual should list all the soil conditions that are available. The Graphics menu contains quick observations of results contained in the output file variations of pile deflection, bending moment, shear and soil resistance with pile depth. See attached screen shot. Loading may be specified as constant or varying linearly with depth. Later on, if you find you are doing these analysis more frequently, then get a copy of “Single Piles and Pile Groups Under Lateral Loading”, 2nd ed.


Testing, Design and Remediation”, F. If not, try to get an experienced colleague to show you the ropes. The program computes deflection, shear, bending moment, and soil response with respect to depth lple nonlinear soils. Values are helpful as nonlinear foundation models in superstructure analysis. You should probably discuss these issues with your geotech.

The program wil generate internally majual nonlinear response of the soil, in the form of t-z and q-q curves for axial loading, in the form of p-y curves for lateral loading.

LPILE Manual

The geotech reports I’ve dealt with never have the cohesion or unit weight. Thanks for all the help: Version 5 allows the manua to define multiple sections with nonlinear bending properties. If you look in the manual, it will give the different parameters for each soil type and recommended values.

The user may optionally ask the program to generate and take into account nonlinear values of flexural stiffness EI. At our firm, we use Lateral Foundation software. AllPile by CivilTech Software has a good soil properties input screen.

When I use it, I’m just determining a point of fixity for the pier design. God, I hope so!!! You just need to thumb through the manual really and you can find almost anything you need there.

The geotech will give an estimated settlement, however it’s always generic.
