The largest moments in a continuous beam or a frame occur when some spans are loaded with live load and others are not. Influence lines are often used to determine which span should and should not be loaded.

A concrete floor system with a ratio of the longer to the shorter span length that is less than 2 is usually considered a two-way system.
