What type of joist support... (Trying again here, having issue connecting via JustAnswer)

can you explain your configuration in a bit more detail?

Customer: replied 11 months ago.
Sure. Follow up from previous help. Need to install new joist into our 747 art project. I've realized that I need to get to a minimum 100# ***** load. I've also realized that where the new staircase is going to be installed I can add some posts for support, plus for transportation purposes I need to run two steel beams underneath the existing deck.The questions are: What size beams to run under the existing joists? What type of spacing for the support posts? And with the additional new joists, if it's not going to be a true 16' clear span but instead has two support beams underneath, what size joists need to be installed? I want the deck to be strong, but 8" C channel is both expensive and very heavy to work with.See attached PDF.

The basic questions and assumptions are on the last page of the PDF. (Probably should have put them on the first page.)

I will reply to the other original question, if that is OK with you.

Expert:  walkereng replied 11 months ago.

Switch to the other. Whatever is the easiest.
