NEG MOM SLAB NOT USED IN COMPOSITE ANALYSIS

 

Purpose:  Used to select assumption for composite analysis behavior. 

 

-->    Given in girder input

 

Specifies the slab is noncomposite for analysis in negative moment regions (assumed to be 20% of the span on each side of piers) for composite dead load and live load analysis.  For Girder System Projects this condition 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.  (Also see COMSPC, NEG MOM SLAB NOT USED IN DEAD LOAD 2 ANALYSIS, NONCOMPOSITE SLAB IS NOT CONTINUOUS BRACING)

 

(Note: This command only affects the elastic section properties for the stiffness analysis. It does not affect the elastic section properties for negative moment stress.)
