The purpose of this section is created to collect the load cases and their max/min load factors accordingly and collects the load modifiers of that limit state.
Each instance is a definition of a limit state combination.(Strength/Service/Fatigue/Extreme Event etc.)

Navigate to Combinations > Design Load Combinations > Limit States

Click three-dots icon on Name cell and click Import OBPAASHTOLimitState.

To import the "AASHTO 9th Edition Load Combination" data into the requested OpenBrIM core memory, simply choose it from the options in the combobox.

In this stage, ou need to define 18 load cases, which are classified into the following categories

For Substructure:

• StrengthI_sub

• StrengthIII_sub

• StrengthV_sub

• ServiceI_sub

• ServiceII_sub

• ServiceIII_sub

• ServiceIV_sub

For Superstructure:

• StrengthI_sup

• StrengthIII_sup

• StrengthV_sup

• ServiceI_sup

• ServiceII_sup

• StrengthIV_sup

For ConstructabilityConstructibility

• StrengthI_cons

• StrengthIII_cons

• StrengthV_cons

For Fatigue:

• FatigueI

• FatigueII

Navigate Load Cases 1 tab

At this point, you must assign the (unfactored load case) Result Extraction Cases (parameters) for the Limit States Components that were defined in the previous step.

Click three-dots icon on DC1 (Noncomposite Dead Load) cell and click Select.

Select DC1_Sub result extraction cases for “StrengthI_sub” as in the figure

Then enter γmax & γmin data.

In order to set DC1 for all limit states, you should perform steps 8 to 9 again.

In same way, keep selecting the load cases for the corresponding limit states

Load cases not included in this example should remain as NULL.
