Given Rise and Run, Using “Riser Limited” Function
for Code Restrictions
Your local code prohibits risers greater than 7-1/2 inches. You need
to build a stairway with a floor-to-floor height of 10 feet 1 inch, a run
of 15 feet 5 inches. Calculate all stair values. Use the “Riser Limited”
function (second function of the
s
key) to calculate a riser height
that does not exceed the stored Desired Riser Height of 7-1/2.”
