`structure pile list`

command

Syntax

- structure pile list keyword <range>
Primary keywords:

apply coupling-confinement coupling-normal coupling-shear coupling-yield element-type force-node group information length model plastic-state plastic-stress plastic-stress-bounds property system-local

Lists properties and responses of pile elements in the range. If no keyword is given, the default output of the command is that associated with the information keyword.

- apply
uniform applied distributed load acting on the element

- coupling-confinement
confining stress acting perpendicular to the element, values acting on the local y and z directions

- coupling-normal
information about the normal coupling springs connecting the pile to the target object (zones in FLAC3D and 3DEC, and particles in PFC3D): displacement, stress and normal direction

- coupling-shear
information about the shear coupling springs connecting the pile to the target object (zones in FLAC3D and 3DEC, and particles in PFC3D): displacement, stress and shear direction

- coupling-yield
yield state of the coupling springs in the normal and shear directions, and the current gap values

- element-type
finite element type

- force-node <keyword>
generalized nodal forces (force and moment) acting on the element. These are the generalized forces exerted by the nodes on the element.

- local
express the values in the element coordinate system (the default)

- global
express the values in the global coordinate system

- group <slot s >
group assignment(s). If slot is specified, then list the group assignment, if any, in slot s.

- information
general element information: nodal connectivity, centroid, surface area, volume, and hide/select status

- length
length of the element

- model
constitutive model

- plastic-state <integration-point ind >
Plasticity state indicators. Each beam element with a plastic material model has a number of integration points distributed throughout its volume, and each of them tracks its plasticity state. The plasticity states at all integration points are listed, unless integration-point is specified. The integration point locations are shown here and here. The plasticity states of the plastic constitutive models can be listed by the

`structure pile cmodel list states`

command.

- plastic-stress <integration-point ind >
Stress for elements with a plastic material model. The plasticity is induced by axial and bending deformations; twisting deformation induces an elastic response. Each beam element with a plastic material model has a number of integration points distributed throughout its volume, and each of them tracks its axial stress. The axial stress is the only non-zero stress component arising from axial and bending deformation. The axial stress (\(\sigma_{xx}\)) is expressed in the beam element coordinate system. The axial stress at all integration points is listed, unless integration-point is specified. The integration point locations are shown here and here.

- plastic-stress-bounds
minimum and maximum axial stress for elements with a plastic material model by checking over all integration points.

- property <integration-point ind > keyword <scaled bscaled >
The properties consist of constitutive model properties, beam-type properties, coupling-spring properties and rockbolt properties. The constitutive model properties are listed by specifying the constitutive property name; these names are not listed here. Elastic-plastic constitutive model properties are stored at each integration point. Such properties are the same at all integration points, except for the softening properties of the strain-softening/hardening Mohr Coulomb constitutive model. The value at a particular integration point is listed by specifying the integration-point keyword — the integration point locations are shown here and here.

Scaled properties are returned if the scaled keyword (FLAC2D

*ONLY*) is set to true (the default is false). If the property cannot be scaled, an error is emitted.Beam-Type Properties
