4.16.2.3. Layer Command¶
- layer(type, *args)¶
The layer command is used to generate a number of fibers along a line or a circular arc.
- layer('straight', matTag, numFiber, areaFiber, *start, *end)
This command is used to construct a straight line of fibers
matTag
(int)material tag associated with this fiber (UniaxialMaterial tag for a FiberSection and NDMaterial tag for use in an NDFiberSection).
numFiber
(int)number of fibers along line
areaFiber
(float)area of each fiber
y & z-coordinates of first fiber in line (local coordinate system)
y & z-coordinates of last fiber in line (local coordinate system)
- layer('circ', matTag,numFiber,areaFiber,*center,radius,*ang=[0.0,360.0-360/numFiber])
This command is used to construct a line of fibers along a circular arc
matTag
(int)material tag associated with this fiber (UniaxialMaterial tag for a FiberSection and NDMaterial tag for use in an NDFiberSection).
numFiber
(int)number of fibers along line
areaFiber
(float)area of each fiber
y & z-coordinates of center of circular arc
radius
(float)radius of circlular arc
starting and ending angle (optional)
