4.16.2. Fiber SectionΒΆ
-
section
('Fiber', secTag, '-GJ', GJ) This command allows the user to construct a FiberSection object. Each FiberSection object is composed of Fibers, with each fiber containing a UniaxialMaterial, an area and a location (y,z). The dofs for 2D section are
[P, Mz]
, for 3D are[P,Mz,My,T]
.secTag
(int)unique section tag GJ
(float)linear-elastic torsional stiffness assigned to the section

section
('Fiber', secTag, '-torsion', torsionMatTag) This command allows the user to construct a FiberSection object. Each FiberSection object is composed of Fibers, with each fiber containing a UniaxialMaterial, an area and a location (y,z). The dofs for 2D section are
[P, Mz]
, for 3D are[P,Mz,My,T]
.secTag
(int)unique section tag torsionMatTag
(int)uniaxialMaterial tag assigned to the section for torsional response (can be nonlinear)
Note
- The commands below should be called after the section command to generate all the fibers in the section.
- The patch and layer commands can be used to generate multiple fibers in a single command.
Commands to generate all fibers:
