The layer command is used to generate a number of fibers along a line or a circular arc.
This command is used to construct a straight line of fibers:
| layer straight $matTag $numFiber $areaFiber $yStart $zStart $yEnd $zEnd |
| $matTag | material tag of previously created material (UniaxialMaterial tag for a FiberSection or NDMaterial tag for use in an NDFiberSection) |
| $numFibers | number of fibers along line |
| $areaFiber | area of each fiber |
| $yStart $zEnd | y and z-coordinates of first fiber in line (local coordinate system) |
| $$yEnd $zEnd | y and z-coordinates of last fiber in line (local coordinate system) |
This command is used to construct a line of fibers along a circular arc:
| layer circ $matTag $numFiber $areaFiber $yCenter $zCenter $radius <$startAng $endAng> |
| $matTag | material tag of previously created material (UniaxialMaterial tag for a FiberSection or NDMaterial tag for use in an NDFiberSection) |
| $numFiber | number of fibers along arc |
| $areaFiber | area of each fiber |
| $yCenter $zCenter | y and z-coordinates of center of circular arc |
| $radius | radius of circlular arc |
| $startAng | starting angle (optional, default = 0.0) |
| $endAng | ending angle (optional, default = 360.0 - 360/$numFiber) |
NOTES:
EXAMPLE:
layer straight $steelMatTag 10 0.11 -b -h b -h; # define steel layer of 10 bars with area 0.11 at bottom of section of width 2b by 2h
layer circ $steelMatTag 10 0.11 0.0 0.0 $h 0 360; # define circular steel layer of 10 bars with area 0.11 uniformly distributed along circumference of circle of diameter 2h
