Member Load Parameters
- Load Case
- Use it to select an
active load case.
Click
to open the Load Cases dialog.
- FX, FY, FZ
- Use these boxes to specify magnitude of concentrated forces in the X, Y, or Z directions of the global coordinate system. By entering the magnitude into a box, you select the load direction. You can select from 1 to 3 directions.
- MX, MY, MZ
- Use these boxes to specify magnitude of moments about the X, Y, or Z axis of the global coordinate system. By entering the magnitude into a box, you select the load direction. You can select from 1 to 3 directions.
- Position x
- Specifies the point on the member where you apply the load. You can enter it as:
- Relative value. You specify Position x as a decimal of the member length, from the start point of a member. For example, 0.50 means that the load acts at the midpoint of the member.
- Absolute value. You specify Position x as a distance, in length units, from the start point of a member.
- Generate a calculation node at the point where a load is applied
- Enhances the display of analysis results at points where loads are applied. Results are easier to analyze then and the point of discontinuity on diagrams of shear forces is easier to spot.
- Coordinate system
-
- Global. Select it to specify a load direction in the global coordinate system.
- Local. Select it to specify a load direction in the local coordinate system of an element to which you apply the load. Used for wind loads or pressure loads.
- Eccentricity
- You specify eccentricity in the local coordinate system. It is the distance of the load from the longitudinal axis of the element (x axis). You can specify eccentricity in the y and z directions. If you do not specify it, the load is applied along the longitudinal axis of the element. Use eccentricity to simulate loads more precisely. You can account for two load components then: a force and a torsional moment.
- Assignment
- Use Direct or Selection mode to assign a load to model elements.
