smrf detailing in low seismic zones
one of the building we are designing is located in a low seismic zone, but because of poor soil type and building occupancy type ibc 2000 requires us to use a special moment resisting frame system. my understanding is that irrespective of the seismicity level since we are using a response modification value 'r' of an smrf, we have to meet all the seismic detailing requirements per chapter 21 of aci-318. is this a correct assumption?
check out our whitepaper library.
the detailing must follow the system used based upon the r selected. so if you detail to a particular system, you must use an r equal to or lower than the r indicated for that system.
