Girder Section: Users have the option to assign a single section or multiple sections to the girder. Multiple sections can be assigned to handle situations where girders have nonprismatic variations. To access the editor, click on the three dots and choose "Edit". Users need to enter a Reference Support Line and Station Difference Along PGL to identify the section's position in longitudinal direction. Then, with the Section input, the desired section along the specified location can be set. Finally, if there is a nonprismatic variation along the girder, the Variation type, such as none, linear, parabolic, or circular, can be specified. When two positions and two sections are given, the variation of the section is applied between these locations and sections. Here are some examples of the different input types:

Haunch Thickness [in]: The additional haunch thickness is measured from both the right and left top flanges. The haunch width is set according to the width of the top flanges of the section. During deck construction, the automatic haunch load computation is impacted by both the haunch thickness and additional haunch width.
