Add Time History Ground Motion dialog
This dialog is used to apply previously defined ground motion time history definitions to the structure.
Opens when the Time History Ground Motion tool is selected in the Loads group on the Model ribbon tab.
Tip: If no time history load definition exists in the model catalog, you will be prompted to create one.
A ground motion is applied globally to all supports as an acceleration type.
Setting | Description |
---|---|
Load | Select the load case or load group to which this load will be added. |
Definition | Select an existing time history definition from this list. |
Start time | Type the start for this load (in seconds). This is with respect to the time zero of the selected load definition. |
Factor | The acceleration amplitude at this joint and direction will be multiplied by this factor (default = 1.0). |
Direction | Select the global direction in which the load is applied. |
