Load Combination & Results Extraction

Load combination and analysis results extraction for steel i girder workflow consists of multiple modular library components. These library objects are;

Unfactored analysis combination (OBPAnalysisCase)

Library Link : https://openbrim.org/objidaziddvhrjxolk0z8zf92xo.libobj?values=LoadType_Input:0%7CisEnvelope:0%7CisIncremental:0%7CisExtreme:0%7CcasesAndFactors:%7C

This library component is a workflow item and is developed for OBP workflow.

The object is created to define unfactored load case combinations/envelopes. With this object, staged construction/deconstruction and other cyclic/static load cases can be combined. This object allows user to filter the case results based on the load type, envelope cases, extract incremental/cumulative results, combine cyclic loads to create most critical load effects.

The name of the core “Combination” object in the library component is added to the name of app instance of the library component.

Limit States (OBPAASHTOLimitState)

This library component is a workflow item and is developed for OBP workflow.

This object 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 (Strength/Service/Fatigue/Extreme Event etc.)

This object collects the OBPAnalysisCase as input for 29 different load cases. However, it is not required to set all of these 29 load cases at the same time.

Beware that the name of core combination object "Comb" is originated from OBPAnalysisCase object and is necessary for result extraction. Thus, if the name “Comb” changes, the CaseObjName parameter must be updated accordingly.
