Purpose: Used to specify web depth or set its limits for design generation.
--> Given in girder design input
Web depth between flanges (vertical projection for box girders with inclined webs), (Default limits: 0.48L-1.2L inches, where L is the span length in feet, or 40L-100L mm where L is the span length in meters). Web depth can be specified (USE WD), or limits can be adjusted (UPPER LIMIT WD, LOWER LIMIT WD) using a single value, or a list of values to vary by web section. With web haunches (see HAUNV , HAUNH , PARABOLIC HAUNCH , LINEAR HAUNCH ) WD is the maximum web depth of each web section.
