[Joe McCormick] After considering the situation a bit more, I agree with Dennis that ignoring the cross wall dead load for shear wall overturning is the best thing to do... But at any rate, I think there is a real difference between a beam atop the shear wall and a cross wall framed into the shear wall. The load path of the beam reaction is down through the shear wall, lateral loading or no lateral loading. The load path of the dead load on top of the cross wall would be straight down through the cross wall studs to the foundation under gravity loading only. The dead load reaction of the beam is on the shear wall prior to any wall rotation. The dead load reaction of the cross wall is not on the shear wall until the wall has rotated sufficiently to pick up the load (effectively eliminating the column action of the studs in the cross wall and turning it into a "beam" resting on the shear wall). Thanks for the helpful thoughts, Joe McCormick ---------- From: Dennis S.
