Effects of higher modes and MDOF on strength reduction factor of elastoplastic structures under far and near-fault ground motions

In seismic codes, the force strength reduction factor is proposed to transform elastic to inelastic strength. The ductility reduction factor, Rμ, plays a key role on R factor if no overstrength is present. The Rμ is determined by SDOF systems. But the higher mode (HM) and Multi-Degree-of-Freedom (MD...
