We want to add a floor to our attic for storage of stuff/junk. Our attic is trussed and we have some concerns over the ability of it to hold it up. Any recommendations?

We also have some wires and pipes running on the trusses and need to floor around these.

3 walls are load bearing and the trusses run from one load bearing wall to the non-load bearng wall (one double wide garage door).

I am wanting to add new subflooring in a garage attic with 2X8 joists that are 16" on center to cover about 15 ft wide and 30 ft long to store many differnt things, some books, clothes, furniture, etc.

Is 20 pounds per linear foot for dead weight and 40 pounds per linear foot for live weight the correct values to use. Will the 2 X 8 joists hold the weight I am planning to do I need to add support?

Can anyone help?

I've got the best answer from a forum a while ago, and it goes like this: "There isn't one. It depends on the age the materials used, the distance between the supports, distance between the joists, thickness of the drywall/plaster…" So it's important that you consider these factors before hoisting things up into the attic for storage. If you're looking for more space, a professional storage facility may also be able to help you! Good luck!
