Purpose: Used to define regions where slab acts and does not act compositely with girder for composite dead load and live load analysis .
--> Given in girder input
A list of spacings (feet or meters) of alternating composite and noncomposite regions, beginning with a composite region, used for the analysis of both composite dead and live loads. Overrides all other data and conditions related to composite regions. For Girder System Projects COMSPC data only is valid for analysis in conjunction with the grid model since the plate and eccentric beam finite element model option requires that the slab be used throughout the length of the bridge for analysis. Stress calculations in either case will use composite/noncomposite regions defined by COMSPC.
