This command is used to construct a straight layer of reinforcing bars.
layer straight $matTag $numBars $areaBar $yStart $zStart $yEnd $zEnd
$matTag |
material integer tag of the previously-defined UniaxialMaterial object used to represent the stress-strain for the area of the fiber |
|
$numBars |
number of reinforcing bars along layer |
|
$areaBar |
area of individual reinforcing bar |
|
$yStart |
$zStart |
y and z-coordinates of starting point of reinforcing layer (local coordinate system) |
$yEnd |
$zEnd |
y and z-coordinates of ending point of reinforcing layer (local coordinate system) |
NOTE: in 2D bending is about the local z-axis
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
