Quote from: HighlandLanding on September 27, 2023, 10:46:54 AMHi New Member Here! Though I've read through other threads and enjoy the content!I am building a second floor to a barn that I have and I'd like to span 16' with 4x6 joists. I am wondering if this is doable. They will be rough sawn true 4x6. The space is a 30'x16' room and I'm trying to avoid having to use center posts. The 4x6 joists will be tied into and sitting upon 2x6 top plates. The 30' will be split equally into two separate rooms and I'm going to use a large LVL in the wall space between the rooms (as in the LVL will span the 16' halfway through the 30'). I also thought that I could incorporate 3x5 steel I beams into the joists for added rigidity (and box them in with rough sawn lumber). What I'm wondering is if this is safe, will they sag, springy floor? I am going to put 2x6 tongue and groove flooring on top. The reason for the short 6" heigh is a space shortage above. I appreciate any and all insight.Thanks,Adam
