I have a second floor I'd like to install this summer - trying to decide on what to use. Right now I'm leaning towards 1x6 T&G boards (with a layer of thin luan on top and a click lock tile system). This will be for light hobbies and storage above the main woodworking area. An architect friend of mine helped me figure out the maximum floor load (100psf) that the structure could take, and put some numbers together for me of deflection at that load depending on wood species - anywhere from .1"-.145".
Additionally, he calculated the maximum load to satisfy L/480 limits - again depending on species that was anywhere from 40-59psf. L/360 54-78psf.
So... as for apparent bounce - do I have anything to worry about? I'm not planning on storing heavy items, but I'm curious if anyone has any opinions on this one way or another.
