Structural

This is a follow up to a previous post I made about pre-engineered metal building modifications.

This building is in SDC D. I am replacing existing rod bracing with a portal frame. The building was built in the 90s. Does the new frame need to meet current seismic detailing requirements? In other words, IMF or SMF?

Otherwise, is there some exception, which would allow an ordinary moment frame to be used?
