2D Fiber Section Orientation

[IsmBaha]

Hi,

I am wondering if there is a way to orient a fiber cross section and rotate it for a 2D problem? For example if I defined a fiber cross section, such as one of these fiber sections: http://opensees.berkeley.edu/wiki/index ... on_Example

Is there a way to rotate it 90 degrees so that the strong axis becomes weak-axis or vise-versa?

I know defining depth as width and width as depth is a way to do it, but I am just wondering if there is any easier way to just orient a section that has already been created.

# t should be y1, y2 and z1,z2 should be d when changing the orientation because it will change #orientation in y-axis and z-axis
set y1 [expr -$d/2];
set y2 [expr $d/2]
set z1 [expr -$t/2]
set z2 [expr $t/2]

section fiberSec $secTagGPb {
# nfIJ nfJK yI zI yJ zJ yK zK yL zL
patch quadr $matID_GP $nft $nfd $y1 $z2 $y1 $z1 $y2 $z1 $y2 $z2
}
