Purpose: Used to define longitudinal web stiffeners.
--> Given in girder input
A list of spacings (feet or meters) for partial longitudinal web stiffeners, alternating between lengths of stiffener segments and spacings between segments. The first value in the list is the distance from the left bearing of the girder to the beginning of the first segment. If a single longitudinal stiffener is used, that stiffener is assumed to be on the compression side of the girder under dead load. (Also see SPLLSW , SPLLST ) LONGSP is used as an alternative to using BLONGSP and TLONGSP.
