To prevent frustration from unneeded steps during calculation launches, beams and girders are pre-screened to determine if they are eligible for live load reduction. Beam and girder elements must meet ***at least one*** the following criteria to be eligible for live load reduction during calculation launch: * Beams: * Supports a non-hosted point load of case Live (LL) or Roof Live (LR) * Supports a non-hosted line load of case Live (LL) or Roof Live (LR) * Supports a hosted line load of case Live (LL) or Roof Live (LR) * Supports a floor with hosted area loads of case Live (LL) or Roof Live (LR) * Girders: * Meets any beam criteria listed above * Supports a point load reaction of case Live (LL) or Roof Live (LR) hosted to a tributary beam * Supports a “Load-Linking” reactions of case Live (LL) or Roof Live (LR) from a tributary beam The use of the above restrictions permit ENERCALC for Revit to clearly determine whether the code provisions for reduction of live and roof live loads are applicable. If none of the above criteria are met, then options for LL reduction will not be presented during the beam calculation launch. ENERCALC for Revit permits only one factor for floor live load (LL) reduction and one factor for roof live load (LR) reduction on a particular beam calculation. These reduction factors will be applied uniformly to all live loads (LL) or all roof live loads (LR) found on the beam. ENERCALC for Revit does not support the ability to reduce individual loads of the same case by differing factors within a single calculation. As a result, if code provisions limit or prohibit the reduction of any specific live load found on the beam, this restriction will necessarily be applied uniformly to all live loads found on the beam. --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.enercalc.com/efr-user-manual/calculation-types/working-with-beam-calculations/beam-loads-16/live-load-reduction/limitations.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
