For a 2hr floor assembly, if you use a large timber beam that is rated for 2hrs, can that beam be hung by exposed metal hangers, if those hangers are painted with 2hr rated intumescent paint?
I had suspension rods on my mind, because I'm going through this on another project (except it's all metal framing and not wood) where they where supporting a floor system from the roof structure using metal rods--I didn't even think of the typical joist hangers.@RLGA, i wasn't quite sure what you meant by suspension rods.
Hopefully with a better system than that KC hotel walkway.supporting a floor system from the roof structure using metal rods--
However, for a 2-hour assembly, how do you plan to show that the wood, let alone the metal connectors, provides a 2-hour fire-resistive assembly?
