Lanes must be defined to analyze a bridge model for vehicle live loads. Lanes are used in the definition of moving load type load cases and in the definition of bridge live type load patterns, which are used in static and dynamic multi-step load case (see Step 12 of the Bridge Wizard). Lanes can be defined with reference to layout lines or existing frame objects. Typically, in this program lanes should be defined from layout lines. Lanes can be defined with width.
Click the Layout > Lanes > Expand arrow command or the Lane Definition item and the Define/Show Lanes button on the Bridge Wizard to access the Define Lanes form and add, modify, or delete a lane definition(s).
