This window is displayed when you create a new analysis or open an existing analysis. It is displayed as a floating window separate from the main application window. Closing this window will not close the analysis itself and will not lose any information about the analysis. To redisplay this window (when an analysis is open), select Analysis Inputs from the View menu, or press F4.
This tab contains inputs for the loads in the analysis. Loads may be grouped into different types of loadings (dead, live, etc.). The grid displays the loads for one loading at a time. Each row in the grid defines one load. See also General Tab, Members Tab, Supports Tab, Combinations Tab, and Notes Tab.
| Loading | The name associated with the loading. This name may be changed to any name not already used. To view the loads for a different loading, select its name from the list. There is always one more entry in the list than there are loadings currently defined. To add a loading, select the last entry in the list and optionally rename it. You may delete a loading by deleting its name and pressing Enter. |
| Load Type | Select either Distributed, Concentrated, Axial, or Moment. Distributed and concentrated loads are applied transverse to the member, whereas axial loads are applied longitudinally. |
| Load Angle | The angle of the load with respect to the cross section coordinate system. For distributed and concentrated loads, an angle of 0 is horizontal to the right, and an angle of 90 degrees is vertically upward. For a concentrated moment, an angle of 0 is a moment about the X axis, and an angle of 90 degrees is a moment about the Y axis. Load angle is not applicable to axial loads. |
| Start Location | The global longitudinal position of the start of a distributed or axial load, or the single position of a concentrated load or moment. Since loads are global (as opposed to local member loads), they may span across multiple supports and multiple members. The start and end locations of an axial load represent the point of application and the point of restraint. |
| End Location | For distributed and axial loads, the global longitudinal position of the end of the load. Not applicable to concentrated loads or moments. |
| Start Magnitude | The magnitude of the load at the start location. For distributed loads, this is a force per unit length. For concentrated and axial loads, this is a force. For moments, this is an applied moment. |
| End Magnitude | The magnitude of the load at the end location. For distributed loads, this is a force per unit length. For axial loads, this is a force, and must be equal to the start magnitude. Not applicable for concentrated loads or moments. |
| Width | For concentrated loads, the width of the load is the length of bearing in the longitudinal direction. Not applicable for other types of loads. |
