Stairs —
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 Inches.
