In the DCA6 you specify a live load = 40psf. I thought the live load requirement for decks and balconies was 100 psf?

It depends what code you are designing in accordance with. ASCE 7 requires 100 psf, while IRC requires 40 psf. Structural members and connections shown in DCA 6 have been sized based primarily on a uniformly distributed floor live load of 40 psf and a dead load of 10 psf. If a deck is not prone to sliding or drifting snow, the criteria in DCA 6 can be conservatively applied to a deck with a uniformly distributed snow load of 40 psf and a 10 psf dead load.
