Function and DirectionSpecify the time forcing function, loading direction and arrival time. Function Name: Select a time forcing function defined in "Time History Functions".Only Force or Moment type functions can be selected. Load Type: Type of the selected time history forcing function Direction: Select the loading direction of the time forcing function. X: GCS X-direction Y: GCS Y-direction Z: GCS Z-direction Arrival Time: "Delay" time for the time forcing function. Enter the delay time when the time forcing function is applied some time after the time history analysis is initiated. For the time history analysis due to vehicle loads, adjust the Arrival Time at each node to consider the effect of moving loads. Scale Factor: Scale factor for the time forcing function After defining the above items, select the nodes to be loaded and click to apply the time forcing function to the nodes. Use "Display" to check the data entry. |
