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 <-GJ $GJ> { |
| fiber... |
| patch... |
| layer... |
| ... |
| } |
| $secTag | unique tag among sections |
| $GJ | linear-elastic torsional stiffness assigned to the section (optional, default = no torsional stiffness) |
| 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:
- The command to generate a FiberSection contains in { } the commands to generate all the fibers in the section.
- The patch and layer commands can be used to generate multiple fibers in a single command.
- In an element recorder you can ask a FiberSection for its 'deformations', 'forces', 'forceAndDeformation', 'fiber $fiberNum $matArg1 ..', 'fiber $yLoc $zLoc $matTag $matArg1 '
