sorry - didn't even see my question here...

So question I had was that I had hvac come by to do some hvac work and he commented the 2x4 spans were shaky going across. This construciton is from original builder. I was wondering if truss construciton like this is normal or if I should support with additional supports? Basically I see 2x4 that are connected by metal plate. Full span of the horizontal piece is like 30 feet.

I would expect them to be a bit shaky along the bottom. Looks like a standard W truss but typically are identical on both sides. They should have been engineered.

Not sure if I follow? Are you saying they weren't done corrctly?

looks like the only thing holding the 2x4 pieces together are the metal plates. Are those good enough or should I reinforce tehse?

also I'm going to put drywall on these.

This appears to be typical, standard truss construction. It would be very surpising for a company to build and sell these without an engineers stamp. They may wiggle side to side but they are not design to not wiggle, they are designed to carry a load from anove. They llok totally fine to me.

I wasn't going to get into any more construction posts, but ------ these look AWFUL to me! Missing W and a plate butt joining 2 pieces of the bottom??? I don't care if you yell at me!!

This is how they are built if they span nore than 20 feet. Have you ever seen a 30 foot 2x4? The stress on that mending plate is horizontal and that plate will not tear.

So no point in reinforcing these? Any harm it can do? Or should I not worry about it? WIll these be able to bear the drywall weight?

Use the lightweight drywall. You are only talking about 1 1/2# per square foot.

So the space is 30' wide and how long? Is it going to be just one big room or will there ne interior walls?
