Clarify modifcation factors for seismic forces
Clarify modifcation factors for seismic forces
(OP)
In the NBC it is unclear to me what to increase the seismic loads by....do you multiply the seismic loads by Rd (Ductility-Related Force Modification Factors) or by Ro (Overstrength-Related Force Modification Factors, or do you multiply Ro and Rd together and use that??
The wording in the NBC is confusing!
