I'm building a 10x32 dock platform. I want to make sure that I properly size my girders.
My dock will consist of driven 12" diameter butt pilings, 4" x 10" rough-cut pressure treated southern yellow pine girders, and pre-cast concrete marine decking.
* Pilings are driven on 8' centers for the length of the dock, 32 feet.
* Pilings are driven on an 11' center for the width.
* Rough-cut pressure treated syp 4"x10" girders are placed on each side of the pilings, across the 11' width, and through bolted using 5/8" timber bolts.
*Concrete (free span) marine panels are placed on top of the griders and through bolted.
* Each pair of girders will be supporting a 4'x8' (1,200 pounds), 4' x 8' (1,200 pounds) and a 2' x 8' (600 pounds) for a total weight of about 3,000 pounds per pair
I've been unsuccessful at finding load tables for the rough-cut lumber. The southernpine.com site has them for dimensional lumber but not rough-cut.
Does anyone have a site with load tables for my application?
Better yet, can one of you structural engineer types give me a thumbs up on the 4x10's?
