The user may thus observe the detailed behavioral measurements of any portion of the depth of each pile sub-group. 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. I have been doing a lot of online researching and reading, so hopefully I can pick it up manula, but it is still a lot of pressure! Loading may be specified as constant or varying linearly with depth.
L-Pile Input Data Thank you! If not, try to get an experienced colleague manua show you the ropes. It took me about 2. Take a look at a soils book and verify. The p-y curves may be printed at any depth for reviews or reference. Several pile lengths may be automatically checked by the program manial order to help the user produce a design with an optimum pile penetration. AllPile by CivilTech Software has a good soil properties input screen.

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.
Several pile lengths can be automatically checked by the LPILE Plus program in order mnual help the user produce a design with an optimum pile penetration. Defense manufacturing is all about project manufacturing and project accounting. Lateral Foundation program uses beam on elastic foundation method Hetenyi with lateral subgrade modulus values.

The program computes deflection, shear, bending moment, and soil response with respect to depth in nonlinear soils. A special subroutine effectively incorporates the influence of layered soils. This feature is used in seismic conditions to reduce the response of liquefied layers or to account for Group Effects. I believe this to be the second most accurate way of performing lateral loaded foundation analysis. The geotech reports I’ve dealt with never have the cohesion or unit weight.
Thank you for helping keep Eng-Tips Forums free from inappropriate posts. 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. Linear interpolation of bending stiffness is computed for piles with varying cross sections. Testing, Mankal and Remediation”, F. This program can provide data for evaluating the pile-cap stiffness, often used by structural engineers for foundation simulation in their numerical models.
Apply a factor of safety of 2. This is a helpful feature for the quick observation of pile behavior subjected to specific increments of lateral loads, bending moments, lateral displacements, or pile-head rotations. Thanks Fixedearth for uploading that kanual about estimating soil lateral capacity.
You just need to thumb through the manual really and you can find almost anything you need there. It is very complex. Reasons such as off-topic, duplicates, flames, illegal, vulgar, or students posting their homework. It’s easy to join and it’s free.

Click Here to join Eng-Tips and talk with other members! The program uses LPile for lateral analyses and also does other analyses.
I have seen some geotech reports where they maual a table with all the info I need for L-Pile is in it, which was really convenient and helpful, but recently, I have recieved two reports that didnt have that. See attached screen shot.
LPILE Plus for Windows: Technical Manual by Lymon C. Reese | LibraryThing
Lpie program allows for up to piles in a group, and each pile can have diffrent EI values in orthogonal directions. We’ve never had the geotech run the program. However, either a manhal or a structural engineer can do the analysis, provided they understand soil structure interaction. Version 5 allows the user to define multiple sections with nonlinear bending properties.
So I am not sure if the ,pile just arent complete, or is it hidden somehwrere and I just dont know? Download Now White Paper: Join your peers on the Internet’s largest technical engineering professional community.
At our firm, we use Lateral Foundation software. In my area of the US the geotech usually runs the L-Pile program because they have more knowledge of the soil parameters.
