DeepFND - Deep Foundation Software

   STRUCTURAL AND GEOTECHNICAL CODES   

 

DeepFND incorporates many international design codes and standards for the design and analysis  (structural and geotechnical) of all wall pile types.

In DeepFND we can perform a service or factored design with the use of US and European standards. We can easily select and change between several US, European, Australian and Chinese structural codes.

• ACI 318-11 and 318-19 (Reinforced Concrere Members)
• ASD 1989 (Allowable Stress Design - Steel Members)
• AASHTO LRFD 13th Edition (Steel Members)
• AISC 360 and 360-Allowable (2010 and 2016)
• EUROCODE 2, 7 and 8 Specifications
• AASHTO LRFD 6th, 8th and 9th
• PEN DOT AASHTO
• European Codes (DIN, BS, XP94, DM, DA)
• Australian Standards (AS 3600, AS/NZS 4100)
• Chinese Standards (CN)
• NYC Building Code
• IBC 2015 standards

   AXIAL AND LATERAL PILE ANALYSIS   

 

DeepFND performs both vertical and lateral pile analysis and includes several bearing capacity equations. Easy recommendations help you select the appropriate method depending on the pile type and installation method. 

For regular piles: DeepFND implements multiple pile installation standards (FHWA GEC-8 and 10, AASHTO Norlund, IBC, NYC Building Code, AASHTO LRFD and more).

For helical piles the software uses both the individual plate and the cylinder methods, reporting the most critical. The general and the Helicap equations can be selected. For the vertical pile design, we can select to use either the Vesic, or the Meyerhoff-Hansen method. DeepFND calculates and checks the helical pile installation torque.

For the lateral pile analysis, DeepFND can use either the defined load on the pile head and calculate the developed moment, shear and pile displacement diagrams, or it can perform a pushover analysis, calculating and presenting the required lateral load to achieve a specified pile head displacement.

DeepFND can perform settlement analysis. In the software we can select one of the implemented pile acceptance criteria, or define our own.

   MULTIPLE PILE TYPES   

 

All pile types examined for axial and lateral design - deep foundations from A to Z, drilled, driven, helical.

Typical piles (drilled, driven, CFA, Caisons etc) can be of any typical shape (circular, square, hollow) reinforced concrete, structural steel or timber (wood). The pile can be normal or belled type. We can define composite pile sections and we can change the pile section along the pile depth.

Helical piles in DeepFND can be of any typical shape (pipes, square solid and square hollow sections). In each pile we can define and assign and unlimited number of helix configurations. The piles can be grouted. Finally, we can use external casing on the pile head, increasing the pile lateral capacity.

• Helical piles (pipes, square solid or square hollow sections)
• Reinforced concrete piles (circular or square section)
• Prestressed Concrete & Sections with GFRP and CFRP
• Steel beams (H piles, pipes, channel sections)
• Belled type piles
• Timber piles (wood)
• Steel core piles
• Composite piles

   SINGLE PILES AND PILE GROUPS   

 

DeepFND can design both Single Piles of any shape and installation type, and Pile Groups with multiple piles (the additional optional module Pile Groups is required).

The software can also design Pile Rafts, considering the combined effect of the soil below the raft (additional module to our Pile Group option).

• Single Piles (Helical and Non-Helical)
• Rectangular Pile Caps
• Triangular Pile Caps
• Circular Pile Caps
• Hexagonal Pile Caps
• Octagonal Pile Caps
• User-Defined Perimeter Pile Caps
• Pile Rafts

   3D FEM   

 

With the 3D FEM module, the user can model any type of pilegroup/pileraft foundation with the advanced finite element method. The module provides numerous ways of automation, rendering the creation of a complex Finite Element model  a straightforward and errorless procedure.  The following modelling options are available:

Soil – The soil medium can be modelled with linear tetrahedral or quadratic tetrahedral finite elements.

Pilecap – Quadratic and linear shell elements are available for the simulation of the pilecaps.

Piles – Piles are modelled as beams (Euler-Bernoulli beam) in accordance with the 3D embedded pile concept. The user can select either a purely elastic behaviour for the pile or a distributed plasticity model based on the slice discretization of the pile section.

There is a variety of material models available:

• Mohr coulomb
• Soil Hardening
• Small Strain soil hardening
• Drucker Prager
• Hoek Brown

   DYNAMIC ANALYSIS   

 

The user can run dynamic time history analysis with both the P-Y method and the Finite element method. Any number of point, linear and area time history loads can be applied on any foundation. Furthermore, earthquake loads in the form of imposed displacement time histories at the boundaries of the soil domain are also available.

   MODEL WIZARD AND DEPTH OPTIMIZATION   

 

The DeepFND Model Wizard can be used to create any deep foundation model in minutes. We can use the Wizard tabs to define all project parameters (analysis settings, pile type and structural section, external loads and design standards). The Wizard creates the model automatically, saving us a lot of time and effort for the initial creation. 

DeepFND has an automatic length optimization tool. The software can use a defined step to increase the pile depth up to a defined depth limit, calculating the axial tension and compression capacity in each step.

   SOIL PROPERTIES - SPT RECORDS - CPT LOGS   

 

Easily define soil types, soil properties and stratigraphies with user-friendly dialogs.

In DeepFND we can create an unlimited list of soils and define all soil properties quickly. The software provides several estimation tools (SPT Estimator and partial estimation tools for each property using scientific methods and equations).

You can directly add SPT Records and CPT Logs, which can be used from the software to estimate various soil properties.

• Define list of soil types
• Define list of stratigraphies (borings)
• Soil properties estimation tools
• Estimate rock properties from RQD
• SPT Records 
• CPT Logs

   EXPORT REPORTS IN PDF AND MS REPORT   

 

DeepFND can generate extensive reports for all examined design sections (piles) and loading stages. The reports in DeepFND are totally customizable - the end user can always select all the report sections included in the final report.

DeepFND reports can include tables and graphs with all examined model properties and calculated results. We can also choose to include to the report all structural design equations and calculation procedure.

The HelixPile reports can be previewed, exported to PDF or exported to Word format, so they can be further edited by the user.
