SDPWS 4.3.5.3-3. requires that perforated shear walls have a maximum ASD capacity of 870 plf (seismic) and 1217.5 plf (wind) for the capacity each side of a perforated shear wall, before the 1.4 wind increase factor is applied. There is also a limit on double-sided shear walls of a total of 1217.5 plf for wind design.
When materials are entered that have a capacity greater than this capacity, the materials’ capacity is reset to the amount. An exclamation mark (!) appears beside the value in the shear results table, and an explanatory note appears below.
