Load Combinations & Crane Loads

Load Combinations & Crane Loads

I have a 10 ton crane inside an enclosed building. I know its considered a Live Load, but do we need to run the crane loads with Geographical loads ( Snow, Wind..)? I have considered this with two other structures in the past, but was wondering if it would be acceptable to just run the two load combinations below.

1. DL + Crane Live Load
2. DL + LL + Crane Live Load

In the past I have run every load combination to cover all possibilities and just wondering if I am wasting time on a load combination that is unrealistic.

RE: Load Combinations & Crane Loads

Crane loads must be combined with snow loads and wind loads in exactly the same way that any other live load would be combined.  IBC does provide some reduction in the combinations when you are working at the ASD level.
