I have broken down the equation to the variables in the IBC2000 and they
Reference table 2305.3.7.2
Here is the equation Co = 100/(A(1-3B)+3B)
Let A= the ratio of maximum opening height to the wall height.
That?s the value across the top of the chart.
Let B= percent of full height sheathing to full length of wall.
That?s the left column on chart.
Co = Shear adjustment factor for V/(full height sheathing)
