Problem 125 Structural.

Does anyone else agree with me that only the weight of the 120 foot long walls should be included in the total seismic weight? Since it specifically says N-S ground motion, the shear in the 60 foot walls stays in those walls, and only the 120 foot long walls weight contributes? Or am i over thinking this problem?

Thanks

 
I don't have that book, but your total seismic weight is independent of the direction of ground motion. I'm guessing that the 60 foot walls you mention are oriented E-W. While they would provide no stiffness in the N-S direction, their weight would still contribute to the seismic force in the N-S direction. Once you add the eccentricity required by code, you'd even get some shear in those walls from a N-S force.
