A PFDC includes post-tensioned (PT) high strength strands running parallel to the beam with friction devices located on the beam flanges. The connection minimizes inelastic deformation to the components of the connection as well as the beams, columns and panel zones, and requires no field welding. Experimental and analytical results show that SC-MRFs with PFDCs have good energy dissipation, self-centering capability, and strength. Past research on SC-MRFs with PFDCs has identified the need to develop a simplified analysis approach to evaluate the actual capacity of this type of system. The paper presents a plastic limit analysis methodology that uses basic concepts of simple plastic theory to estimate the actual lateral capacity of SC-MRFs with PFDCs.
