XIS

 

Purpose:  Used to define bottom flange stiffeners on box girder. 

 

-->    Given in girder input

 

Flexural moment of inertia of each box girder bottom flange stiffener about the base of the stiffener  (in4 or mm4 ).  Can be given as a list, or a single value for all segments.  Must be given if stiffener is to be determined effective according to AASHTO Articles 10.39.4.3.1 (ASD), 10.51.5.4 (LFD) and 6.11.3.2.1 (LRFD).  If XAS , XCS and XIS are specified, stiffeners contribute to section properties of the girder.
