The aim of the paper is to assess the usability of nonlinear simplified methods for practical application for
regular and irregular frame structure with different stories. The behaviour of regular and irregular, four and eight
multi-storey RC frames, were analyzed using pushover analysis which allows for a more realistic estimation of
seismic demands of multi-storey buildings. Nonlinear modeling and analysis allows more accurate determination
of stresses, strains, deformations, internal forces and displacements of critical structural components, results that
can then be utilized for the final design of the frame components or evaluation of the building global strength
capacity and ductility. Numerical modelling of nonlinear behaviour is carried out by applying plastic hinges and
the model with inelastic fibers. Estimation of target displacement is performed using capacity spectrum method,
equivalent linearization method, coefficient method and displacement modification method. ...Comparative
analysis of pushover curves obtained with plastic hinges model and structural model with inelastic fibers are
performed.
