The application of the extended N2 method for a typical eight storey reinforced concrete wall building
has been studied, which is due to its layout at the limit of the applicability of N2 method. In the master
thesis analysis and design of the main load-bearing elements as well as the modelling for the nonlinear
analysis and non-linear analysis itself have been performed. For dynamic analyses 10 different
accelerograms with two horizontal components were used. Parametric studies of the structure’s
behavior for several different combinations of earthquake loading directions and for two earthquake
loading intensities were performed. The comparison of the parametric study results with the extended
N2 method results confirmed that the extended N2 method provides adequate and reasonable results to
the user. Also it has been shown that the extended N2 method is simple enough for use in every-day
engineering work. In addition, it was demonstrated that the choice of the earthquake loading direction
is important. Different combinations of the direction and sign of two components of the same
accelerogram can yield quite different structural response. In the master thesis some problems related
to dimensioning of structural elements and to the preparation of a non-linear model are pointed out.
Difficulties related to fetching and evaluating the large amount of data obtained when performing a
non-linear time history analysis suggest the advantages of the N2 method.
