Auto Load Generation: Centrifugal Force Screen

This screen is used for auto generating centrifugal force. Click Generate on the Loads: Load Data dialog for a CF case in AASHTO Standard or CE in AASHTO LRFD code.

For this generation, you can select one of the available live loads. The available list is based on the loads in the vehicular library. You can modify/add vehicle loads in the library. In addition to vehicular load, you need to specify the radius of the curve and the direction in which to apply the loads. If the center of curve lies to the right of bridge when looking upstation, specify the load to be in -X direction. Otherwise specify it to be in +X direction. If the pier is at skew program will compute load as two components. One along X and one along Z.

The manual input option allows you to specify the total live load (per lane) to use for computations of centrifugal force.
