General
Load Combination Table: The load combination table is used to map the analysis result cases and their corresponding factors to the template, along with the limit states. It serves as the basis for all finite element analysis results used in the code check equations.
Check For[StrengthServiceFatigue/Construtibility]: The code check component only allows for either a constructibility or a strength-service-fatigue limit state check in a single run. Therefore, if the user intends to perform a constructibility check, the finite element results that need to be mapped will likely differ significantly from those required for a strength-service-fatigue limit state check.
Include Haunch For Section Properties ? [Yes/No]: According to DOT requirements, haunch area may or may not be included in the sectional property computations. When haunch is included, it increases the inertia and section modulus and decreases the stress values, making the calculation less conservative. When the option "Include Haunch for Section Properties" is set to "No", the dimensions of the haunch are still used to determine the locations of the deck and girder sections. As a result, entering a larger haunch depth can lead to a higher section modulus, even though the option to include the haunch is set to "No".

Modular Ratio: If the Modular Ratio Comp. Method is defined with the option 'User Input,' a modular ratio can be defined manually. Otherwise, this parameter will be marked as not applicable (N/A).
Fatique Parameters
ADTT: The annual daily truck traffic is a parameter used in fatigue checks.
Number of Lanes Available to Trucks: Number of lanes available to truck is a parameter used in fatigue checks.
Ductility Parameter
Including the haunch in determining Dt [YES/NO]: This parameter can be used to specify whether the haunch will be included in ductility checks within the code checks. Since including the haunch is optional, the total depth is calculated based on the actual haunch depth if this parameter is set to 'Yes', or calculated conservatively if set to 'No'.

The ductility-related code check can be performed either by making a conservative calculation or by directly using the modeled haunch depth. The screenshot below provides an example of excluding the haunch in determining Dt, with the parameter set to 'No'

Deflection
As specified in AASHTO 2.5.2.6.2, "The live load portion of Load Combination Service I of Table 3.4.1-1 should be used." Additionally, you can directly set a deflection case.
