A suitable Structural Pointset for the Profile shown in the Examples of Parameterization image would be created as follows:
|
NEW PTSSET /UBPTSE |
Create new Structural Pointset |
|
NEW PLIN /UB-TOS |
Create P-line element for top of steel |
|
PKEY TOS |
Define key |
|
PLAXI Y |
Direction of P-line along positive Y axis |
|
PY (0.5 * PARA[1]) |
Distance in Y direction from component origin = half overall height. (There is no need to set PX, because it is zero.) |
|
CLFLA TRUE |
Display P-line in centerline representation |
|
TUFLA FALSE |
but not in tube representation |
|
NEW PLIN /UB-BOS |
Create new P-line element for bottom of steel |
|
PKEY BOS PLAXI -Y PY (-0.5 * PARA[1]) CLFLA TRUE TUFLA FALSE |
|
|
NEW PLIN /UB-NA - |
Create new P-line element for neutral axis |
|
PKEY NAXI PLAXI Y CLFLA TRUE TUFLA FALSE |
|
|
END |
Make the Structural Pointset the current element |
|
NAREF /UB-NA |
Define neutral axis reference |
Note:
All the P-line attributes may be defined on one line. Reference information concerning
the setting up of the P-line attributes is given in Defining an Axis to Controlling the Appearance.
