I have a one story building approximately 230'x230' with steel braced frames, pretty symmetric layout. I am puzzled by results of Response Spectrum Analysis. When acceleration is in on X-direction, there is sizable total base shear (more than 60% of X direction base shear) in the perpendicular Z-direction. Does this make sense? Shall the sum of support reactions in Z-direction be zero, when there is no acceleration and external force in Z-direction? Otherwise equilibrium does not hold in the Z-direction.

Thank you very much for your responses.
 
How is you analysis being performed, if it takes into account torsion maybe that is the cause? If it's software, maybe you aren't understanding the output?

I would think more information is needed to understand what might be happening here.
