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, uplift plate, 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, lateral capacity, and group analysis all together. Users only need to input the data once instead of several times in different programs. AllPile makes pile analysis easy, 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.
- 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. The torsion capacity is the sum of horizontal skin friction around shaft.
- Lateral analysis uses the finite-difference method to model soil-structure interaction. Under lateral loading, pile shaft deflects and pushes the adjacent soils. Therefore, lateral resistance (pressure) is generated between soils and pile. By integration of lateral pressure, shear, moment, rotation, and deflection, the pile and soil interaction and behavior are analyzed. This is the same method used in COM624 program of FHWA. Comparing COM624, Allpile provides great user-friendly interface, additional features, and improvements. AllPile creates a COM624 input file and output. The input and output files can be directly viewed and printed. For comparison, you can directly run COM624 of HFWA yourself using the input files created by AllPile. AllPile is also comparable with Lpile (© Ensoft Inc.), which is also based on COM624. In our tests, AllPile generates very similar results as Lpile or COM624.
- Group analysis is based on matrix method for pile group under vertical, lateral, and moment loading. It analyzes settlement, rotation, and deflection of pile cap and each pile’s behaves under group condition. Group analysis only handles symmetrical pile layout with one type of pile.
- Shallow foundations are for foundation under vertical, lateral, and moment loading. Bearing capacity, settlement and rotation are calculated. The method is recommended in “Principles of Foundation Engineering” Braja M. Das.
- Shaft analysis can handle large size drilled shaft with or without belled bottom. The method is based on “Construction Procedures and Design Method” recommended by FHWA .
