AllPile is a
Windows-based analysis program that handles virtually
all types of piles, including steel pipes, H-piles,
pre-cast concrete piles, auger-cast piles, drilled
shafts, timber piles, jetted piles, tapered piles, piers
with bell, micropiles (minipiles), uplift anchors, and
shallow foundations.
One of the major advantages AllPile has over other pile
software is that it combines most pile analyses in a
single program. It calculates compression (with
settlement), uplift, and lateral capacity all together.
Users only need to input the data once instead of
several times in different programs. AllPile makes pile
analysis both economical and time-efficient.
AllPile is suitable for all engineers, even those
without too much pile analysis experience. It helps
structural engineers choose soil parameters, and
geotechnical engineers choose pile properties. AllPile
is a must-have tool for structural, geotechnical, and
construction engineers.
CALCULATION
METHOD
Vertical analysis is based on the approaches and methods
recommended in FHWA, AASHTO, and NAVY DM-7 (NAVFAC)
manuals. The compression capacity is the combination of
skin friction and tip resistance. The uplift capacity is
the sum of skin friction and pile weight.
Lateral analysis uses COM624S, which uses the same
methods as COM624 of FHWA with some improvements. It
uses the finite-difference method to model
soil-structure interaction. AllPile is a pre-process and
Windows interface of COM624S, which is fee in the
package. AllPile creates a COM624S input file and calls
COM624S internally. COM624S input and output files can
be directly viewed and printed. For comparison, you can
directly run COM624 yourself using the input files
created by AllPile (COM624 is downloadable from HFWA).
AllPile is also comparable with Lpile (© Ensoft Inc.).
In our tests, AllPile generated the same results as
Lpile.
KEY FEATURES
Smart Data Find – Users only need to select N-value (SPT)
from a sliding bar. The program then automatically
searches into its database to find the other soil
parameters that are necessary for the analysis, such as
friction, cohesion, density, subgrade reaction
coefficient, and P-y parameters. For users with limited
field data, they can just input SPT or any one of the
parameters and let the program find the remaining data.
Interactive Input – The graphical interface changes
simultaneously with the inputs to illustrate the pile
profile. Pile head and load are graphically presented to
help users to input data quickly and accurately.
Vertical Capacity – The program evaluates the uplift and
compression capacity of the pile.
Settlement – The program calculates pile settlement at
design load based on the values of point load, skin
friction, and shaft compression.
Point of Fixity and Stiffness – AllPile determines the
Point of Fixity and Stiffness of the pile.
Lateral Capacity – AllPile performs lateral analysis
under different head-load boundary
conditions. Deflection, moment, and shear along the
entire length of the pile are presented
graphically in the report.
Group Piles Analysis – Both vertical and lateral
analyses handle group piles. The loads can be vertical,
compression, uplift, shear, moment, and torsion. The
program calculates lateral
movement, rotation, and settlement of the pile cap.
Batter Piles and Sloped Ground – The program can handle
batter piles and sloped ground.
Seismic and Static Conditions – Circular and static load
conditions can be selected in the
lateral analysis.
Negative Friction – The program computes the downdrag
force formed by settlement of soft
layers.
Zero Friction – AllPile handles no-friction sections of
the pile, such as tieback free bond length.
Section Calculation – The program calculates the section
properties for reinforced or hollow
piles. It has a built-in database for all available W
and H steel piles.
Graphical Presentation – AllPile presents the results
using high quality graphics, which can be inserted
directly into a report. Users can customize the format
of the report.
Export to EXCEL – AllPile results can be exported to
MS-EXCEL graphics and reports by a few mouse clicks.
Users can modify the reports and graphics easily.
English and Metric Units – The program accommodates both
English and metric units.
More Features Are Coming – CivilTech will continue to
add new features and improve the
program in response to users' comments and
recommendations.
