Vehicle classes must be defined to analyze a bridge model for vehicle live loads using a moving load load case. A vehicle class is simply a group of one or more vehicles for which a moving load analysis is performed (one vehicle at a time).
Click the Loads > Vehicle Type > Vehicle Classes > New command or the Vehicle Definition item and the Define/Show Vehicle Classes button on the Bridge Wizard to display the Define Vehicle Classes form.
Note: Whenever a Vehicle definition is created, CSiBridge automatically creates a Vehicle Class of the same name, containing only that single vehicle definition with a scale factor of 1.0. The automatically created Vehicle Class definition cannot be modified or deleted except by modifying or deleting the vehicle definition.
