class o3seespy.command.patch.Circ(osi, mat, num_subdiv_circ, num_subdiv_rad, center, rad, ang)[source]

Bases: PatchBase

The Circ Patch Class

This is the command to generate a circular shaped patch

Initial method for Circ

Parameters

  • osi (o3seespy.OpenSeesInstance) –

  • mat (obj) – Material object associated with this fiber (uniaxial_material object for a fibersection and ndmaterial object for use in an ndfibersection).

  • num_subdiv_circ (int) – Number of subdivisions (fibers) in the circumferential direction (number of wedges)

  • num_subdiv_rad (int) – Number of subdivisions (fibers) in the radial direction (number of rings)

  • center (list) – Y & z-coordinates of the center of the circle

  • rad (list) – Internal & external radius

  • ang (list) – Starting & ending-coordinates angles (degrees)

Examples

>>> import o3seespy as o3
>>> osi = o3.OpenSeesInstance(ndm=2)
>>> center = [1.0, 1.0]
>>> rad = [1.0, 1.0]
>>> ang = [1.0, 1.0]
>>> conc_conf = o3.uniaxial_material.Concrete01(osi, fpc=-5.0, epsc0=-0.005, fpcu=-3.5, eps_u=-0.02)

class o3seespy.command.patch.Quad(osi, mat, num_subdiv_ij, num_subdiv_jk, crds_i, crds_j, crds_k, crds_l)[source]

Bases: PatchBase

The Quad Patch Class

The patch command is used to generate a number of fibers over a cross-sectional area. Currently there are three types of cross-section that fibers can be generated: quadrilateral, rectangular and circular.

Initial method for Quad

Parameters

  • osi (o3seespy.OpenSeesInstance) –

  • mat (obj) – Material object associated with this fiber (uniaxial_material object for a fibersection and ndmaterial object for use in an ndfibersection).

  • num_subdiv_ij (int) – Number of subdivisions (fibers) in the ij direction.

  • num_subdiv_jk (int) – Number of subdivisions (fibers) in the jk direction.

  • crds_i (list) – Y & z-coordinates of vertex i (local coordinate system)

  • crds_j (list) – Y & z-coordinates of vertex j (local coordinate system)

  • crds_k (list) – Y & z-coordinates of vertex k (local coordinate system)

  • crds_l (list) – Y & z-coordinates of vertex l (local coordinate system)

Examples

>>> import o3seespy as o3
>>> osi = o3.OpenSeesInstance(ndm=2)
>>> crds_i = [1.0, 1.0]
>>> crds_j = [1.0, 1.0]
>>> crds_k = [1.0, 1.0]
>>> crds_l = [1.0, 1.0]
>>> conc_conf = o3.uniaxial_material.Concrete01(osi, fpc=-5.0, epsc0=-0.005, fpcu=-3.5, eps_u=-0.02)
>>> o3.patch.Quad(osi, conc_conf, num_subdiv_ij=1, num_subdiv_jk=1, crds_i=crds_i, crds_j=crds_j, crds_k=crds_k, crds_l=crds_l)
op_type = 'quad'
class o3seespy.command.patch.Rect(osi, mat, num_subdiv_y, num_subdiv_z, crds_i, crds_j)[source]

Bases: PatchBase

The Rect Patch Class

This is the command to generate a rectangular patch. The geometry of the patch is defined by coordinates of vertices: I and J. The first vertex, I, is the bottom-left point and the second vertex, J, is the top-right point, having as a reference the local y-z plane.

Initial method for Rect

Parameters

  • osi (o3seespy.OpenSeesInstance) –

  • mat (obj) – Material object associated with this fiber (uniaxial_material object for a fibersection and ndmaterial object for use in an ndfibersection).

  • num_subdiv_y (int) – Number of subdivisions (fibers) in local y direction.

  • num_subdiv_z (int) – Number of subdivisions (fibers) in local z direction.

  • crds_i (list) – Y & z-coordinates of vertex i (local coordinate system)

  • crds_j (list) – Y & z-coordinates of vertex j (local coordinate system)

Examples

>>> import o3seespy as o3
>>> osi = o3.OpenSeesInstance(ndm=2)
>>> crds_i = [1.0, 1.0]
>>> crds_j = [1.0, 1.0]
>>> conc_conf = o3.uniaxial_material.Concrete01(osi, fpc=-5.0, epsc0=-0.005, fpcu=-3.5, eps_u=-0.02)
>>> o3.patch.Rect(osi, conc_conf, num_subdiv_y=1, num_subdiv_z=1, crds_i=crds_i, crds_j=crds_j)
