Example of Defining a Structural Pointset
A suitable Structural Pointset for the Profile shown in Figure 5:3.: Example of Parameterisation for a Universal Beam Profile 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 centreline 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
Notice how 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.
