REX PilesDefinition of a pile calculation modeltaking into
account the elasto-plasticpile-soil interaction
REX Piles is the add-in for Autodesk Robot Structural Analysis
which allows includingthe elasto-plastic pile-soil interactionin
the analysis of structures supported on piles.
It lets you account for pile-soil interaction by calculatingthe
distribution of horizontal and vertical ground reaction modulialong
the pile shaft and by specifying elastic characteristics of the
pile base support.Distributions of ground reaction moduli are then
changed to characteristics of supportsand generated in Autodesk
Robot Structural Analysis as a system of elastic
supportsdistributed along the member axis.
The most important software features:offers a wide range of pile
types and pile manufacturing technologiesanalyzes single piles and
pile groupsdefines an arbitrary soil profilepresents data and

Scope of Calculations:REX Piles is used to analyze the pile-soil
interaction for different pile types. Calculationsare performed for
a single pile or a group of piles, vertical or inclined (at an
angle up to45 degrees).Definition of the pile parameters is based
on geometrical data of a member selectedin Autodesk Robot
Structural Analysis: length, cross-section shape (circular,
square,rectangular or composed) and cross-section dimensions (such
as radius and sidedimensions).Afterwards, you specify parameters of
the type and technology of pile manufacturingand define layers of
soil where the pile is situated.After the required parameters are
defined, REX Piles calculates variability of the reactionmoduli
Kx(z) and Kt(z) along the pile shaft and the characteristics of the
elastic supportof the pile base Kp, Kb and Kr.The pile-soil
interaction is represented in the calculation model by a system of
elasticsupports distributed along the member axis and elastic
supports of the pile base. Elasticsupports perpendicular to the
pile shaft (with the stiffness kx) express the soil reactionto
lateral displacements of a pile, while tangent supports (with the
stiffness kt) - thesoil reaction to longitudinal displacements. The
pile-soil interaction through the pilebase (pressed piles) is
represented by the elastic supports: axial (with the stiffness
Kp),perpendicular to the axis (with the stiffness Kb) and
rotational (with the stiffness Kr).Finally, REX Piles sends
information about a number, distribution and characteristicsof
elastic supports to Autodesk Robot Structural Analysis. As a
result, you obtaina calculation model of a pile which accurately
represents real work of the pile in theground.
