A methodology is presented for modelling the inelastic torsional response of buildings in
nonlinear static (pushover) analysis, aiming to reproduce to the highest possible degree the
results of inelastic dynamic time history analysis. The load vectors are defined using dynamic
elastic spectral analysis while the dynamic characteristics of an equivalent single mass
system, which incorporates both translational and torsional modes, are derived using an
extension of earlier methods based on the SDOF approach. The proposed method is verified
for the case of single-storey monosymmetric buildings.
