proejuan,
Per the IBC the seismic forces up to and including Seismic Design Category B should be considered to act separately and independently in each of the orthogonal directions. In Seismic Design Category C and above the orthogonal combination of loads must be considered using either the SRSS or 100%/30% rule. In the IBC section 1620.3.2 describes this. The UBC has similar criteria.
