Development of efficiency index for steel moment frames with Self-Centering Connections

Traditional earthquake-resistant systems are dependent on the inelastic response of the building members. These systems experience significant residual displacements after major earthquakes due to seismic energy distribution all over the building and make their repair uneconomical. Self-Centering sy...
