This design guide provides an in-depth review of rain loads and ponding effects to help design professionals properly and efficiently design for ponding on roofs constructed with structural steel, open web steel joists, and joist girders. It includes several recommended methods of analysis that can be used to consider the effects of ponding, methods of design accounting for ponding effects, and a presentation of the SJI Roof Bay Analysis Tool. These methods are thoroughly discussed and then demonstrated with many helpful design examples.
