This commnand 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 command to generate FiberSection object contains in { } the commands to generate all the fibers in the object. To construct a FiberSection and populate it, the following command is used:

section Fiber $secTag {
fiber...
patch...
layer...
...
}


$secTag unique tag among sections
fiber... command to generate a single fiber.
patch... command to generate a number of fibers over a geometric cross-section
layer... command to generate a row of fibers along a geometric-arc


NOTES:

  1. The command to generate a FiberSection contains in { } the commands to generate all the fibers in the section.
  2. The patch and layer commands can be used to generate multiple fibers in a single command.
  3. In an element recorder you can ask a FiberSection for its 'deformations', 'forces', 'forceAndDeformation', 'fiber $fiberNum $matArg1 ..', 'fiber $yLoc $zLoc $matTag $matArg1 '
