Version 5 allows the user to define multiple sections with nonlinear bending properties. The structural engineers like manuao because you can combine the loading and the soils description into one entry format.

Posting Guidelines Promoting, selling, recruiting, coursework and thesis posting is forbidden. The report or an addendum would provide lateral movements to the structural engineer. The main difference is the analysis approach. See attached screen shot. L-Pile Input Data We’ve never had the geotech run the program.

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

manua, However, either a soils or a structural engineer can do the analysis, provided mabual understand soil structure interaction. Is there a book that you recommend, that I can get these tables and info, for soil classification, from?

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. This is often an iterative process requiring communication between the structural and geotechnical engineer.

The help manual should list all the soil conditions that are available. Click Here to join Eng-Tips and talk with other members! The program uses LPile for lateral analyses and also does other analyses.

L-Pile Input Data Thank you for your help. The program will consider the nonlinear bending stiffness EI of each pile during computation. This program can provide data for ,pile the pile-cap stiffness, often used by structural engineers for foundation simulation in their numerical models. Few years ago, I used to grind teeth when I had to do Lateral loaded pile lpild Liquefaction analysis.

LPILE Plus has the capability to perform push-over mabual and can study the pile behavior after the development of plastic hinges yielding. I will check out the help manual. A set of distributed lateral loading may be applied anywhere along the length of the pile. The program computes the distribution of loads combination of vertical, lateral, and overturning moment in up to three orthogonal axes from the pile cap to piles arranged in a group.

The program can internally compute the deflection, bending moment, shear, and soil resistance as a function of depth for each pile. Values are helpful as nonlinear foundation models in superstructure analysis.

Several pile lengths may be automatically checked by the program in lpilf to help the user produce a design with an optimum pile penetration. The p-y curves may be printed at any depth for reviews or reference. I believe this to be the second most accurate way of performing lateral loaded foundation analysis. L-Pile Input Data Thank you!

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 of lateral load capacity you should be getting? Join your peers on the Internet’s largest manhal engineering professional community.

Students Click Here Join Us! The user may optionally ask the program to lpule and take into account nonlinear values of flexural stiffness EI. The method proposed by Budhu and Davies,? These two programs yield very close results. Linear interpolation of bending stiffness is computed for piles with varying cross sections.

Promoting, selling, recruiting, coursework and thesis posting is forbidden. This book explains SPT values and analysis of laterally loaded piles and piers.

This is a helpful feature for the quick observation of pile behavior subjected to specific increments of lateral loads, bending ,pile, lateral displacements, or pile-head rotations. My first questions is, I dont quite see all classes of soil in L-pile, so what can I use for what? You just need to thumb through the manual really and you can find almost anything you need there.

The program computes deflection, shear, bending moment, and soil response with respect to depth in nonlinear soils.

These are from “Soil Engineering: More importantly, the program plots the force and displacement on the pile cap, such as the axial force tension and compression of each pile on the pile cap, llateral forces shear and moment of each pile on the pile cap, and the displacement of the pile cap in different directions.

N is the number of blows per foot Lpil believe. The graphical observation of output curves features a new interface that allows zooming of areas manula particular interest.

Loading may be specified as constant or varying linearly with depth.

LPILE Plus v / GROUP v (3-D)

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.

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! 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. FORUM8 will distribute them.

The program wil generate internally the 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. It took me about 2. Thank you so much for the help! Soil behavior is modeled with p-y curves internally generated by the computer program following published recommendations for various types of soils; alternatively, the user can manually introduce other p-y curves.
