> Subject: perforated plywood shear wall equation (improved)
> Thanks again.
> 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)
