Line data: Applied loads |
Applied loads may be defined at multiple points along the line.
The $x$, $y$ and $z$ coordinates define the point of application of the applied load. The $z$-coordinate represents the arc length at which the load is to be applied, measured relative to either end A or end B, as specified. The $x$ and $y$ coordinates are relative to node axes. The load is applied at the node whose reference arc length is closest to the specified $z$-coordinate.
| Warning: | If a line uses line feeding or is partly inactive, then the actual arc length at which the applied load acts may vary as the designated node approaches a line end at which feeding occurs. A warning will be reported if this is the case. |
When torsion is not included, the $x$ and $y$ coordinates take the value zero and are not editable.
The reference arc length of the node where the load is applied.
The loads are applied either with respect to global axes, or with respect to local node axes, according to the selected load type.
The components of the applied loads. Each of these components may be constant, vary with simulation time or be given by an external function.
If torsion is not included, any applied moments are ignored since the line cannot respond to them. In order to model the response to applied moments, you must include torsion.
