Snow Load, Partial Loading
Snow Load, Partial Loading
Continuous beam systems shall be investigated for the effects of the following three partial-loading cases, as specified in [1]:
Case 1: Full balanced snow load on either exterior span, and half the balanced snow load on all other spans.
Case 2: Half the balanced snow load on either exterior span, and full balanced snow load on all other spans.
Case 3: All possible combinations with full balanced snow load on any two adjacent spans, and half the balanced snow load on all other spans. For this case, there are (n−1) possible combinations, where n is the number of spans in the continuous beam system.
Accordingly, MkaPEB considers these cases when applying snow loads to continuous beam systems (purlins).
1) Full balanced snow load on either exterior span, and half the balanced snow load on all other spans.
2) Half the balanced snow load on either exterior span, and full balanced snow load on all other spans.
3) All possible combinations with full balanced snow load on any two adjacent spans, and half the balanced snow load on all other spans.
