Parameters of point load applied into a node are:
|
Name |
Is used for identification of the load. |
|
Specifies the base direction of the load. The direction may further specified by the Angle item. |
|
|
Type |
The point load may be a force load, wind load, snow load, or predefined load. |
|
Specifies the angle by which the load is rotated from its basic direction. |
|
|
Specifies the size of the load. |
|
|
System |
Defines the co-ordinate system in which the load is applied. For information about setting a local co-ordinate system of a node see chapter Geometry > Nodes > Defining a local co-ordinate system of a node. |
Items Direction and Angle may be combined together to obtain the required orientation of the load. The Direction specifies the base direction. The Angle then defines if and how the load is inclined from the base direction.
The syntax for item Angle is:
R[axis of rotation][angle]
E.g. Rx30 means to rotate the load around the X-axis by 30 angle units. Rz-20 means to rotate the load around the Z-axis by minus 20 angle units. The angle units can be adjusted in program Unit setup.
The meaning of the Value depends on the Type of load.
For Force load, the Value is the real value of the load.
For Wind load, the Value represents the loading area. The real wind pressure is defined by wind curve specified in the project settings.
For Snow load, the meaning is analogous to Wind load.
For Predefined load the meaning is analogous to Wind load.
