I've read several of the topics on the overstrength factor, but they mostly refer to steel (brittle bolted connections vs ductile connections).
How about if I am designing a concrete moment frame for gravity and seismic forces? Overall I divide my seismic forces by R. Given those forces, I can straightaway design, say, the midspan using those seismic forces? For connections, I multiply the connection seismic forces by Omega (to almost negate the R factor)? Do I only need to multiply by Omega for special and intermediate moment frames?
