Point Load
Add a
Point Load
to points for concentrated forces or moments at points. The loads are defined in the given coordinate system.
Point Load
Enter values or expressions for the components (
x
,
y
,
z
for 3D models and
x
,
y
for 2D models) of the point load
F
P
.
The
F
P
list normally only contains
User defined
. When combining the Beam interface with another physics interface, it is also possible to choose a predefined load from this list.
Point Moment
Enter values or expressions for the components (
x
,
y
,
z
for 3D models and
z
for 2D models) of the point moment
M
P
(3D) or
M
l
z
(2D).
Linear Buckling
To display this section, click the
Show More Options
button (
) and select
Advanced Physics Options
in the
Show More Options
dialog box.
If you are performing a linear buckling analysis with a combination of live and dead loads, select the
Treat as dead load
check box to indicate that the load contributions from this node are constant. The default is that a load is proportional to the load factor.
For more information about live and dead loads, see
Buckling Analysis
.
•
You can add the
Phase
subnode to specify the phase of this load in a frequency domain analysis.
•
You can specify this load to be a
Harmonic Perturbation
in a frequency domain analysis.
•
You can assign this load to a load group. See
Load Cases
in the
Structural Mechanics Modeling
chapter.
