I'm sure someone has posted about this before, but I'm having trouble finding it.
I'm designing a temporary construction platform out of wood. The contractor is proposing 2X4 posts at 4' O/C (in the weak direction). I've seen this on construction sites before, but am unable to get this to work with the 200 lb point load requirements. Flexure isn't close, never mind the connection to the platform.
I suppose my question is, how is this allowed on construction sites? Does OSHA have scaffolding load criteria for rails that differs from the 200lb point load? Im not having a lot of luck searching around.
Thank you for your help.
