How much weight will a deck with 2x6 joists 16 oc support?

A deck with 2x6 joists spaced 16 inches on center (oc) can typically support a live load of around 40 pounds per square foot (psf) and a dead load of 10 psf, totaling approximately 50 psf. The exact weight capacity will depend on factors such as the type of wood used, the length of the joists, and local building codes. For more precise calculations, it’s advisable to consult a structural engineer or refer to local building codes.
