    In this case, your joists are adequate to support a 30 psf live load and 10 psf dead load. Use span tables for progressively heavier loads until you find the limits of your floor. In this example, the table for a 40 psf live load/10 psf dead load floor shows that the joist in the example have a required Fb value of 1,644 and an E value of at least 2,400,000.
