The Span Type offers multiple choices to select from:
Simple Span: The Simple Span option allows you to specify information for only one span at a time.
Multi Span (continuous): The Multi Span (continuous) option should only be selected if the live loads and dead load on composite are to be treated as acting on the continuous spans, and you would like the program to design the deck reinforcement in the negative moment zone.
Multi Span (non-continuous): The Multi Span (non continuous) option allows you to enter a series of simple spans, and treats all superimposed dead and live loads as acting on the Simple Span model only.
Multi-Span (Mixed): The multi-span (Mixed) allows you to model and analyze multiple units of superstructure in a single LEAP Bridge concrete file.
