In the Seismic Load Effects equation (ASCE 7-02 eq. 9.5.2.7-1)
E = rho Q(sub E) + .2 S(sub DS) D
From a number crunching standpoint, for a steel frame building (standard AISC double angle connections for typical beam to column connections) with X-bracing located symmetrically around the perimeter of the structure, can the HORIZONTAL component of the Seismic force (rho Q(sub E))generate a vertical load in an interior column which supports only gravity loads and is not part of any of the braced frames?
I would think NO.
All of the examples that I have access to however, calculate a vertical load from the horizontal seismic force but they always utilize moment frames in the example.
Any thoughts would be appreciated.
