Moment Resisting Frame

The RSFJ in Moment Resisting Frames are installed at the end of the beams. 


There are two different types of applications: the first one is where the RSFJ is installed both at the top and bottom of the beam, the second one is where the RSFJ is installed only at the bottom of the beam. The advantage of the dual RSFJ installation is that the length of travel of the RSFJ is halved for a given drift. 

The initial stiffness of the RSFJ (below the Fslip value) provides rigid moment beam connections that contribute to decrease the beam sizes.
