Simplified seismic design procedure for steel MRF structure with nonlinear viscous dampers

This paper presents a simplified design procedure (SDP) for performance-based of low-rise new steel MRF buildings with nonlinear viscous dampers. The SDP uses an effective stiffness and equivalent damping multi degree-of-freedom (MDOF) model the building, which is established using linearized system (damping devices associated bracing). integrated process to achieve target performance objectives. consistent analysis procedures in ASCE 7–16 seismic conventional structures without dampers, however, differentiated from dampers computation period ratio as function ductility demand on structure. was validated dynamic time history analyses (NDTHA) results 4-story example building two scenarios damper arrangements building. MRFs were designed various base shear strength levels (i.e., 100%, 75%, 60%, 50% 40% required 7–16), sized added control story drift response. presented this show that objectives can be selected achieved smaller than MRF.
