approximate design dead load of stairs
i need to know a good estimate on the weight (psf) of steel bar grate stair treads & stair stringers. i have a stair imposing loading on a slab. i need to check the slab for the laods, but i don't know what the dead loads are for stairs of this type. i just need a safe ballpark assumption.
try c10x15.3 stringers with 15#/ft for handrails and 9.4 psf for bar grates.
