The Pile Group worksheets assume a minimum of 2 piles and a maximum of eit 75, , or piles for a pile group. 2. This program uses the "elastic method" of analysis, assuming that the pile cap is in fact "rigid", so that the applied loads are linearly distributed among the piles.5/5(1). PILE GROUP ANALYSIS PROGRAME - excel web share T stars based on 35 reviews "PILEGRP" is a spreadsheet program written in MS-Excel for the purpose of analysis of pile groups with rigid caps using the ".
included in GROUP and the user should be familiar with that technology. A complete discussion of the method of analysis of a single pile under lateral loading is given in the documentation for LPILE, another program distributed by ENSOFT, Inc. The lateral load behaviour of a piles group was studied by Ruesta and Townsend () in Stuart, Florida. The pile group was composed of prestressed concrete piles in a 4 x 4 arrangement that were spaced at three pile diameters. Read More.

Pile group analysis spreadsheet program written in MS-Excel for the purpose of analysis of pile groups with rigid caps using the "elastic method". Specifically, the properties of the pile group are calculated, and then based upon the applied vertical and horizontal loadings, the. Innovative Geotechnics is an engineering company with the aim of researching and developing geotechnical design and analysis programs.
Innovative Geotechnics provides innovative geotechnical design tools for soil-structure interaction and deep foundation problems such as single piles or pile groups under lateral and vertical loads.
A brief outline is given of the basis of analysis used in two computer programs, PIGLET and DEFPIG, for analysis of pile group response.
A comparison of the capabilities of each program is. Report No. UT RESPONSE, ANALYSIS, AND DESIGN OF PILE GROUPS SUBJECTED TO STATIC & DYNAMIC LATERAL LOADS By: Kyle Rollins, Ph.D.
Ryan Olsen. A brief outline is given of the basis of analysis used in two computer programs, PIGLET and DEFPIG, for analysis of pile group response. A comparison of the capabilities of each program is presented and then a parametric study is made of a six‐pile group to illustrate the.
Consider a group of three piles, each of mm diameter installed in one row. This arrangement represents n × m pile groups, where n = 1, 2, 3, etc. and m = 3, Fig. vertical pile was analyzed under a lateral load of 80 kN using relationships developed by Reese and head pile was assumed, the resulted pile head displacement is by: 8.
This is a spreadsheet program written in MS-Excel for the purpose of analysis of pile groups with rigid caps using the "elastic method". Specifically, the properties of the pile group are calculated, and then based upon the applied vertical and horizontal loadings, the vertical and horizontal pile reactions are calculated.
Analysis and design of pile groups 29 1 the ratio of load on pile to the average pile load in the group (P / P av), and is plotted against the normalised pile spacing (s/d).
GROUP is a well-accepted tool for analyzing the behavior of pile groups subjected to both axial and lateral loadings.
The program was developed to compute the distribution of loads (vertical, lateral, and overturning moment up to three orthogonal axes) applied from any multiple locations in the pile cap to piles arranged in a group. Main Features Analytical solutions.

Diagrammatic Geological Model (Adopted from Ahmad Abdelrazaq et al., ). From the available borehole data it was assessed that the geological proﬁle is very heterogeneous.
The site lies entirely within an area of reclamation, which is understoodFile Size: KB. The users can view deformed shape of pile group once the analysis is successfully completed.
Extensive displaying options such as model contour, pile and pile cap color, local and global axes, shape scaling factor and pile numbering are available in PileGroup for the users to Operating System: Windows. Ultimate vertical load bearing capacity of pile analysis is done by Static Analysis based on c-ϕ values in which vesic’s bearing capacity factors are used for cohesive and cohesion less soils.
The problem of a laterally loaded pile embedded in soil is closely related to the beam on an elastic foundation. The fourth edition of this well-known book is fully revised and up-dated. It deals comprehensively with every aspect of design and construction of all types of piled foundation.
A key feature of this book is the large number of worked examples, many of which are based on actual problems encountered in practice.3/5(3). Screw-pile and pile - kb.

Pile group Analysis $ Analyze a group of piles for loads in any direction using the same advanced soil-structure model used in the Static Pile program.
Piles may be located at different elevations and be battered independently. Add to cart. Categories: Individual Products, Under $/5(1). Provides methods of analysis of pile formation that may be useful in design.
Presents: a consistent theoretical approach to the prediction of pile deformation and load capacity; parametric solutions for a wide range of cases; demonstrations of how such solutions can be used for design purposes; a review of the applicability of these approaches to practical problems.3/5(1).
Structural design of reinforced concrete pile caps The strut-and-tie method extended with the stringer-panel method December A.V. van de Graaf In the finite element analysis, the pile cap collapsed because of a shear failure.
This failure mechanism cannot be predictedFile Size: 1MB. (1) Pile Group Analysis (CPGA) which is a stiffness analysis of three- dimensional pile groups assuming linear elastic pile-soil interaction and a rigid pile cap. (2) Pile Group Graphics (CPGG) which displays geometry and the results of CPGA.
(3) Pile Group Stiffness (CPGS) which determines the pile head stiffness coefficients for a. The capacity of a pile group is obtained by using an efficiency factor. If the pile group contains 16 piles and capacity of a single pile is 30 tons and the group efficiency is found to bethe group capacity is tons.
High pile group efficiency is desirable; the question is how to improve the group efficiency.Soil Pile Group Interaction in FB-MultiPier Dr. J. Brian Anderson, P.E. Developed by: Florida Bridge Software Institute –Lateral p-y multipliers –Axial efficiency factors •Example #2 Pile Group Analysis – Load Test at Roosevelt Bridge.
Coupled Soil-Structure Interaction C., and Reese, L. “Lateral Load Behavior of a Pile Group File Size: 1MB.Thus, the pile group efficiency is equal to the ratio of the average load per pile in the group at which the failure occurs to the ultimate load of a comparable single pile. Efficiency of a pile group can also be obtained by using Converse – Labarre formula: Where m = number of rows.
n = number of piles in a row. d = diameter of pile end.
