A study on the capacity of ductility and energy dissipation of Special Moment Resisting Frames (SMRFs)

Special Moment Resisting Frame (SMRF) is one of the most ductile and energy dissipating Seismic Force Resisting Systems which uses the bending strength of moment resisting of frames to oppose the lateral force of earthquakes. It is expected that the bending stiffness of beams and columns assembled to construct these bending frames, and the strength of beam-to-column connections are some of the most important parameters which affect the amount of the maximum drift, ductility, and energy dissipation of structures. In this paper, the capacity of ductility and energy dissipation of SMRF systems are studied. For this purpose, four single story-single bay Special Moment Resisting Frames constructed of different Reduced Beam Sections (RBSs), are analyzed using non-linear finite element method under cyclic loading according to AISC Seismic Provisions 2010 and the results are compared.
