Panel Type [InteriorPanel/EndPanel]: The terms "end panel" and "interior panel" are used to describe the sections of a steel girder plate that are positioned at the ends and interior sections of the girder, respectively, as depicted in the accompanying figure. The interior panels comprise the remaining segments of the girder that lie between the end panels.

Result Case to To Find Points of Permanent Load Contraflexure: According to AASHTO 6.11.1.1, the effective span can be determined differently for simple spans and continuous spans. For continuous spans, the effective span length should be calculated based on the points of contraflexure of the major axis bending moment under permanent loads, or by considering both simple supports and points of contraflexure. Following this approach, it is necessary to specify the result extraction case that represents the permanent loads to identify the points of contraflexure and, subsequently, the effective spans. This parameter is used to define the result extraction case to be applied in calculations related to contraflexure.

Deck Rebar Material: This parameter can be used to specify the material used for the deck rebars.
Concrete creep adjustment factorCreep Adjustment Factor: To incorporate the effects of concrete creep in stress calculations that involve the application of long-term loads to the composite section in regions of negative flexure, the area of the longitudinal reinforcement can be conservatively adjusted by dividing it by the "Concrete creep adjustment factor." The concrete is assumed to transfer the force from the longitudinal deck steel to the rest of the cross-section, with concrete creep acting to reduce that force over time. It is important to note that assuming a value greater than 1 is a conservative approach and is not mandated by the AASHTO LRFD BDS. As such, it is not recommended to use this assumption in normal design practice. When using the default value of 1, the reinforcement area will remain unaltered.
