Purpose: Used to define longitudinal web stiffeners.
--> Given in girder input
A list of spacings (feet or meters) for partial top longitudinal web stiffeners, alternating between lengths of stiffener segments and spacing between segments. The first value in the list is the distance from the left bearing of the girder to the beginning of the first top stiffener segment. (Also see SPLLSW , SPLLST ) TLONGSP and BLONGSP are used as an alternative to using LONGSP.
