Interior Shear Wall E1-E2
The stiffness of the interior CMU shear wall is not needed for the mezzanine forces. It is
calculated here so that the shear force tributary to the wall line may be assigned to the individual
wall piers based on their relative rigidities.
1 inch = 25.4 mm
1 foot = 0.305m

∆ abc
∆ abc = 0.00042 in
Subtract strip BC:
∆ bc ∆ f( 8 .ft ,30.ft )
∆ bc = 0.00011 in
∆ a ∆ abc ∆ bc
∆ a = 0.00031 in
