Welcome to Truss Tuesday! Every Tuesday, we will present and interesting truss and/or loading situation to see if you can figure out if it works or not. None of these trusses will be actual productions trusses, we just want to have a little fun. We will follow up with the answers on Thursdays.

It would indeed hold the chandelier, but you would have to decide whether it’s a good idea. B1 is at 100% capacity with a 1000lb concentrated load at the vault’s center. Make sure you purchase quality hangers for that fancy chandelier!
