Moment Frame - Rigid & Pinned connection
Moment Frame - Rigid & Pinned connection
(OP)
I am designing a special steel moment frame building with 2 bays in one direction. Due to the wide flange column configuration I cannot do a moment frame with fixed ends at each column. Looking at a bay I have two beams connecting with a pinned connection to the outer columns and connecting rigidly (moment) to the center column, thus two half frames. I am designing this under the 06' IBC and the AISC 341-05 seismic provisions for SMF (special moment frame) conditions.
Does anyone know if there is a code violation of not using a frame fixed at both ends?
Thanks in advance.

Under lateral load it works kind of like outriggers in a high rise, one external column goes into tension and the other into compression.
I wouldnt use 2 half frames though it is virtually a mechanism.
