Purpose: Used to define concrete barrier attributed to a girder to stiffen it for serviceability and fatigue stresses.
--> Given in girder input
Area (in2 or mm2) of concrete barrier to be included in girder stiffness for calculating positive moment composite serviceability and fatigue stresses. Default is zero. Barrier stiffness defined by BARIO , BARCEN , BAREA is applied only to girder input for which it is given.
