Structural connections are established between lane-load points and structural objects such that vehicle live load may transfer to the superstructure. These structural connections, while shown graphically, are not rigid members, but rather are imaginary lines used to redistribute loading according to tributary geometry. Structural connections are made between lane-load points and two frame objects by projecting perpendicular from reference lines. A cantilever connection is made to a single frame object if only one frame is available. Please see the Influence-based moving-load analysis implementation article for an explanation of how lane-load points and structural connections enable moving-load analysis.
