SDPWS values for shear walls other than wind/seismic

SDPWS values for shear walls other than wind/seismic

SDPWS values for shear walls other than wind/seismic

(OP)
I have an unusual condition where a shearwall panel sees a net in-plane shear due to gravity loading.

The 2007CBC Table 2306.4.1 notes used to apply reductions to the tabulated allowable shear values for loading conditions other than seismic. For example a 1.4 increase for shear due to wind loads or a 0.63 reduction factor for shear due to D+L. SDPWS 2005 nominal capacities don't seem to include any reference to reductions in capacity for shear coming from D+L loading. For the wind and seismic capacity comparison I can get correspondence from ASD to LRFD values for the CBC2007 to SDPWS2005. There is a "lambda" of 0.8 to be included in the factored capacity but this seems to net a much smaller reduction than I would have expected.

Does anyone know if there is another reduction to be applied or a reference that may help?

thanks,
Michel
